This was very confusing at first and I only managed to do some things by accident (clicking around and pressing E randomly). After reading the comments and giving it another try I figured it out a bit more, but it still feels unfinished and not very fun.
The game sent my GPU fans spinning, probably a good idea to limit FPS and/or resolution for game jams.
BTW I’m on Linux so this took some fiddling to get running: I think if you marked the upload as being for Windows (and maybe used zip instead of 7zip), I could have just installed it through the itch.io app, which I was running through Steam/Proton.
