This game is really cool, I liked the idea that you were going through bosses of the afterlife to prove you weren't dead!
That being said I am not very good at this game and couldn't get past the judge I understand the gameplay decision to only have one life but man I would have been able to see way more of the game if I had a few more tries at a boss. I liked not having to worry about shooting or being on target as the bullets homed to the enemy boss which allowed me to focus on staying out of the bullets.
It looks like this game was made pretty quickly given it was submitted in mostly 24 hours after jam being open which makes me wonder where this project could have grown over the course of development time. I cant tell if its a stylistic choice or was an unfished art style on purpose but I don't see why the gatekeeper or judge for that matter would be these somewhat randomly color outline while the player is a black on white outlined character maybe the bosses were just sketches and rather than focus more time into this project you left it? Regardless they dont look bad I just think they seem a little out of place for an otherwise dreary setting for the game.
