Yeah, I ran out of time to implement some core mechanics. I'm unsure if I'm allowed to make major updates like that (so far all the updates post-submission date were bug fixes), but if so I'll definitely try to add more if I have time. I decided to submit it anyways since it's at least "playable" and better than submitting nothing, and gives sort of a small preview of the game. So yes, sadly right now all you can do is explore and sleep.
