Really cool game! Loved the concept and the puzzles. Definitely engaging. I have 2 minor critiques which are:
- Adding some coyote time would make the jumping feel a bit better
- I did not like how I had to restart the whole level if I ran out of corpses, I would have liked to be able to "reclaim" the last corpse so if I flubbed a jump I didn't have to redo the setup
Very minor critiques, but otherwise I liked this game a lot! Excellent entry!
Edit: I also just saw that this is your first game jam and first serious game in Unity. You should be proud, you did an excellent job!
