Ha, that was really fun. I liked the vibe of the space station, the aesthetic was consistent and the sound design was on point (though I would've loved some background elevator music, lol). A few minor bugs/notes:
- Near the end of the game, the SFX started glitching out and repeating. Not sure what was up with that, maybe too many entities in the scene? Not sure how you're handling all the coal that gets generated/consumed.
- Some of the vocal parts were a bit hard to decipher due to the clanging/reverb, but that's part of the charm too I feel.
- I wasn't sure what the threat of the cube was. It didn't seem that hard to manage its size while also keeping the furnace full. Maybe if there was more reward/punishment behind furnace level management, or the cube posed more of a pressing threat, this would feel more impactful.
- The economy was a bit unbalanced (though, it's hard to get that right for a jam) in that increasing shovel capacity seemed like always the best bang for buck. Increasing coal production rarely seemed to help (there was always lots of coal when I went over, at least) though I'll admit I didn't optimize my strategy/movement super well.
Overall I really liked this game, it was super unique and cool! I think it has a lot of potential, and could be really fun if you added other jobs, cranked up the stakes, and turned it into a multiplayer game! Great work!
