My first note for you: great job on the thumbnails and screenshots. Its the reason I chose to play your game. I love this low-ish poly style and the mono-chrome is design is aesthetic. And it looks even better in game. The opening camera sequence does a great job of establishing immersion in the world from the beginning
I might have enjoyed the "dash" more if the sound was a little softer and if it let you travel a little further or faster. I was stuck at this for a while and was mashing it a lot.
I really like what you did with the integrated tutorial and allowing the player to learn and figure out out naturally. The first playable screen with the character frozen was a very easy to understand intro (which is very important for a jam game)
I also thought it was really original how you took an new approach to death (or self explosion) not always being a respawn. It definitely made me feel like i might be a demon or in hell or something (along with the aestheic)
Great job! I read the description after playing. Solo dev in 48 hours, second finished game, first jam. I'm impressed!
