Well made! Nice jam entry.
I liked the animations on the enemies and players. Those all felt really smooth. I never quite got used to the controls. It all felt a tiny bit floatier than I wanted, resulting in a lot of platforming frustrations. However, the larger frustration was the checkpoints. Dying in one hit on a screen you've never seen and being forced to go back to the start almost made me quit the game at the tutorial level. Is there a reason it can't be a room my room checkpoint? There's merit to making things difficult, but combining tricky maneuvers with one-hit deaths that make you repeat the tricky rooms again feels bad. Also, I had a few deaths where bullets from past rooms followed me and hit me when I was trying to assess the new room. That was super frustrating.
Overall, this is a super well polished jam entry and a great little game. Well done and congrats on completing the jam!
