The game is ambitious (surely too much for a jam), but the concept is cool!
I think you know there are some bugs:
In my first run I get stucked in an area from which I could not climb back up.
In my second attemp I drowned in an indescribable emptiness ahaha
Anyway hope you will update this, you nailed the mood even if it is a prototype
If you try mine, let me know what you think!
