This is really great! Anything I would say negatively about it would be nitpicks or pure jealousy. This plays well, looks great, and sounds incredible.
I ended up dying on (I think?) the last level and the game crashed for me. I wasn't able to continue my save, but honestly? It didn't even detract that much from the experience for me!
I also found a small bug that is actually worth pointing out: on the first orange level, if you go down a level and then back up, you can get the consumable reward infinitely by trying to go back to the checkpoint / resurrection pillar (I was trying to resurrect someone).
I don't say this about every entry (you can check my post history!) but I really hope you continue with this game and turn it into a full release. This is really excellent!
