v0.5

Added Harpy Wingmaiden
Added Harpy Raptor
Added Harpy Duchess
Added Marionette

Reworked tilemap, each tile is now stored in a dictionary by its x,y position and tile lookups resort to raycasting as a last resort.

v0.12

N/A

v0.11

– Added Goblin

– Added Goblin Raider

– Added Goblin Shaman

– Added Goblin Lord

– Added new map (0-5)

– Added stomach system, allowing units to have any number of different “stomachs.” (Only used by Goblin Shaman’s UB skill at the moment.)

– Units now gain permanent incremental stat increases each time they digest prey. Being digested will also transfer a portion of a unit’s accumulated stats to their predator.

– Units in barracks may now passively devour (NPC) vessels while you are out on missions. This is mostly to make the base feel more alive and will be expanded later, with “Caught red-handed” dialogue and tie-ins with the base system that will affect passive predation and stat growth rates.

– Each class now has a set chance of eating or showing up as prey in the aformentioned way (Prey are spawned from the ether, not taken from the players barracks.) Certain factors may affect these rates, such as the unit being set as secretary.

– All buffs and debuffs have been reworked, and many will no longer appear in the skill list. In a coming update, hovering over a stat on the status menu will show an exact breakdown of the buffs and debuffs affecting it.

– Encumbrance debuffs have been consolidated into a single skill and now operate on a sliding scale based on max capacity.

– Base movement has been increased to 5

– Feed menu digestion skip has been sped up significantly

– The way images are displayed has been changed, fixing transparency issues on units such as the lamias. This method is much less efficient, so it may lead to performance issues right now, but it will get polished more in the future.

– In preparation for adding mid-battle saves, units now contain Guid references to each other in battle rather than direct ones.

– Classes that may be used for either battles or the lobby will now use StorageInfos to reference either UnitStorages or UnitInfos

– Each unit now contains their own Stats, which are added to their classes’ stats. Stats are now universally contained in arrays and referenced through ints, for easier coding.

– Some text codes, have changed, I’ll have notes on these once modding is reenabled.

– Bios are now fully contained in the Speech class, making editing easier and finally allowing for modded units to be given their own bios.

– Role, race, and species tags added for each class that will allow for better differentiation for each respective case down the road.

– Events in the EventScene have been deconstructed, allowing for much more modular event creation

– The stun per turn inflicted on a pred is now reduced directly by their struggle.

– Leveling up in battle now increases struggle and max stun by 5% each.

– Being overburdened now reduces unit’s Skill to 0, but still allows them to take an action.

– Healers now heal prey each turn instead of after a digestion period.

– Healers and carriers may now release their prey at any time using Expel.

– Enter, Expel, and Digest are now available from the main move/attack menu.

– Enter has been renamed to Shelter and can now be used even after taking actions.

– A file named game_log.txt that will display error reports has been placed the main game folder to make bug reporting easier.

– Finished image layering system, fixing blurriness and misaligned art for Chateau and Avalon.

– Reworked statuses to be more modular and gave them the ability to have custom removal conditions.

– Some bugs with Patra’s dialogue have been fixed.

– Healthbars now disappear during digestion.

– If an existing status is inflicted again, it will now reset the duration instead of creating a separate instance.

– Tripping playing generic battle dialogue has been fixed.

– Lobby buttons can no longer be interacted with while you are being digested.

– Culture has been temporarily hardcoded to be English, which should hopefully fix some errors in other regions.

– Enter now displays a green tile, indicating it is safe.

– Entering sandbox will no longer erase your squad.

– Number of units displayed in lobby now updates after feeding Cheshire.

– Cheshire should now have her stomach state and weight reset after battles.

– You can no longer feed yourself to your secretary if she has already eaten prey when returning from barracks/shop/etc.

– Confirm window is no longer functional during enemy turns.

– Images in the gacha results screen will now appear at the correct aspect ratio.

– Hamburger menu will now be disabled when the rest of the lobby is disabled.

– Corn’s class icon will now show her as prey instead of pred.

v0.1

Gameplay Changes:

– Added main menu and basic commander creation.

– Added save/load system.

– Added gacha (Note: The lamias have been temporarily added to the gacha to fill space, but they will be obtained in a different way in the full game.)

– Added shop (Note: While the shop has been added, items do not currently have any functionality.)

– Added new unit: Cheshire. While not usable in battle yet, Cheshire has dialogue for additional scenarios involving the commander being fed to her.

– Lamias are now playable in battle and can be fed to other units, as a side effect of being added to the gacha. Their combat dialogue may be strange in some places, however.

– Vessels will now be leveled up individually, as a temporary bugfix for the save system.

– Possibly a few other things

– Various bug fixes

Other Stuff:

– The way the UnitStorage class is handled has been changed quite a bit. Stomach will no longer store other UnitStorages, but instead Guid references to them. In addition, the UnitDatabase class now only stores a single list of units instead of splitting them into being active and inactive.

v0.04 Beta:

Change list:

Gameplay changes:

– Added new vessel: Patra

– Added new vessel: Avalon

– Added new skin: Training Date Theano

– Probably some other stuff

v0.03a:

Sorry about the short delay! Here is the v0.03a update!

Note: In sandbox mode, the ‘P’ key will now open the debug menu while in free-cam mode.

Change list:

Gameplay changes:

– Added new vessel: Sampo

– Added new vessel: Chateau (IMPORTANT: Chateau’s weight gain is not fully implemented yet)

– Added new class: Carrier

– All characters now have weight gain (Except Cornucopia)

– Custom squad selection implemented. Squad members will be highlighted and cannot be fed to other units

– Units will now carry over their stats from the lobby into battle. Units retain half of their weight between lobby and battle scenes. In addition, all pending digestions will be completed and the list of units digested will be updated

– Units lost in battle will now be removed from the lobby

– The battle will not be counted and the game state will remain the same if the player loses or manually returns to the lobby

– Units can now be locked

– The player can now replenish all vessels at any time from the lobby menu

– Banners added for mission start/clear/fail states

– Clearing or failing a mission will now cause all allies/enemies to immediately digest their prey before returning to the lobby

– Added a new “Hard Mode” map to use upgraded units on. Note: This map hasn’t been extensively tested or balanced in any way.

– Pressing ‘O’ while in sandbox mode will now delete units

– Covenant and Theano’s weight gain have been revamped. (Similar to Schrodinger’s.)

– Speed up button has been added during digestion animation in lobby.

– Dream sequence graphic has been updated.

– 0-3 modified slightly

– Various bug fixes

Other Stuff:

– Characters’ scale in-game is no longer dependent on their source image

– AI has been reworked to allow for more complex decision-making. This is important for future enemies, but the effects of this are very minimal, at the moment

Known issues:

– Game lags at the end of enemy turns. This is likely dependent on the number of units on the map.

– For unknown reasons, some players have the story cutscene freeze and are forced to skip it. I have not been able to figure out why yet.

– Assorted problems associated with Schrodinger’s vial toss.

– Enemies occasionally move in the wrong direction?

– It is entirely possible that KO’d units spitting up their prey may still cause the game to crash.

– Forgot to make the two extra wild lamias in 0-3 face the right direction.

v0.02a:

NEW FEATURE: SANDBOX MODE

Clicking on the event banner on the lobby will now allow you to enter a sandbox battle. Exiting the base menu by right-clicking and then pressing the ‘p’ key in this mode will bring up the debug menu, where you can freely place units and alter their stats.

Change list:

Gameplay changes:

– Added three new characters (Lamia, Wild Lamia, Dusk Lamia)

– Characters can now have multiple separate stomachs

– Added temporary weight gain to the game. (Will reset at start/end of battle, currently only applies to new characters)

– Hovering over a unit will now display their move/attack range

– Added story cutscenes into the battle scene

– All messages and battles can now be skipped by right clicking

– Story scene can also be fast-forwarded by right clicking. This will be replaced by a proper skip button later.

– Finished adding Schrodinger and Covenant’s attacks/skills (Minus the teleport effect of vial toss)

– The X in the status view window actually works now

– Speech bubbles in lobby now display when there are multiple text boxes

– A few balance changes. Covenant in particular has been buffed

– Various bug fixes

Other stuff:

– Multiple events/skill activations can now be queued. For example, if multiple Schrodingers are digested at a time, their vial skills will queue up and trigger in order. (Buggy. If the game freezes after a unit’s action it’s probably because of this. Please let me know if it does.)

– Reworked AI, making it more diverse and giving me the option to code it for each unit individually

– The AI still has a lot of flaws, so I’m probably going to rewrite it entirely for the next update

– Rewrote a lot of old code and reworked how several things were done to make things more consistent and easier to work with in the future

v0.02:

Early access to the v0.02 build has been released on Patreon!

Gameplay Overview:

This is a Pre-Alpha, so many of the assets are still placeholder. This includes the enemies, so enemy dialogue may be somewhat strange!
Despite the gacha theming, this will be a standalone single-player game with no micro-transactions.
Units can be defeated by being eaten and digested (Over the course of several turns.) Digesting a unit will give the predator EXP and restore their Health and Energy.
Each unit has a certain stomach capacity, and will lose speed and movement for each other unit they swallow. Units can swallow other units up to one above their capacity, at which point they will become immobilized.
Units with a single prey in their stomach can still be eaten.
Units will become easier to vore the lower their HP is. If a predator’s HP is reduced to 0, all units inside them will be freed and they will no longer be able to move or resist vore.
In the lobby, you can set your favorite vessel to be your secretary. Secretaries have three different sets of lines depending on whether they are unfed, have swallowed the Commander, or have eaten other vessels.
In typical gacha fashion, vessels can be upgraded by feeding them other vessels.
There is currently no interaction between the lobby and battle scenes, though there will be eventually.
