The premise of the story is that a university expedition of speleology students, led by a professor, heads out to investigate an interesting cave…
And then a collapse happens. Jenny ends up cut off from the main group, trapped alone in an unexplored section of the cave.
Well… alone. Almost alone. Or not alone at all.

Changelog:

0.05

Added an overlay system for Jenny. Right now the overlays only include clothes — a tank top and shorts. In the future, I plan to use this more for cosmetic effects and things like that. There is a black clothing set and a white one in the inventory: the black one works, but don’t touch the white one yet
Yes, inventory. Now you can actually see something in it. It doesn’t have much practical use yet, but you can use it to dress Jenny, check what items she has, and read their descriptions.
Added a status button. Its functionality is not implemented yet. Later, it will give access to additional information about the character, her clothes, and so on.
Added a map that allows you to teleport to locations on the map without having to walk there manually.
Added two more tomb scenes. If Jenny is wearing clothes, the scenes will work differently — basically, all the most interesting parts will be skipped. I did this for immersion. I’m pretty sure nobody will go there dressed anyway.
I left the first tomb scene unchanged, even though I originally wanted to change it. For now, it stays as it was. There is no clothed version for it yet.
Also fixed a bunch of bugs and added some new ones

0.04

Fixed repeating and stuck messages like “This door is already open” that were showing multiple times
Added an option to permanently enable navigation highlights (can be toggled in Preferences)
Added two new scenes
The random event mentioned earlier was NOT added. That system relies on the same foundation as the buggy message system. Basically — I’ll implement it next time. Fixing the messages had to come first.

0.03

The tomb storyline has been further developed.
You can now access a second location inside the tomb.
You can wash under the waterfall.
And there is one more scene at the end, in a dream.

0.02

Added several story events related to exploring the cave.
Added a new location — the tomb (that’s what Jenny calls it; it may not actually be a tomb).
Added two scenes.
Added a quest journal (currently in a simplified form — the map is still planned for later).
Added ambient sounds.

0.01

Two more locations have been added to the cave (four if you count reverses).
With this, the major cave construction is complete – though there will still be background updates and other cosmetic improvements.
A couple of animations have been added to the sleep scene (including a continuation that was previously missing).
An inventory system has been added (it’s not useful yet, but it’s already in place).
The quest journal is technically implemented, but it will only become available in the next update because I want to combine it with the map and notes – Jenny will have a notebook where all of this will be displayed.
The map will also allow teleportation in case you get tired of running back and forth – and since that feature isn’t ready yet, the journal isn’t available either 🙂
