I really liked the mechanics at play here. Let me first say that I really liked this entry. Its strongest suits are its concept, and its art. Both of those were executed quite well. However, I do have a few notes for improvement.
My biggest problem with the game is the movement. I will be blunt, the character feels very janky and awkward to move. This is entirely because of the lack of any form of inertia at play, it makes small movements and air control feel clunky. If you were to improve anything about this game, I'd want it to be that.
I also think some bug fixing could be due. A few that I ran into are crashes when restarting levels, awkward physics behaviour when standing on top of crushers, corpses not obeying the laws of gravity, and music not being set to loop.
I think though that given a few days to fix the aforementioned issues and you would have a fantastic product on your hands, so please take my words as encouragement.
Thank you for creating!
