Hey, really cool concept! Good use of minimalist visuals paired with a great soundtrack - especially for the boss fight. I would have liked to see more variation to the gameplay, perhaps some other ways to stop or reverse time. As it stands, the game feels like it's unsure whether it wants to be a bullet hell shooter or a puzzler. The narrative should also be clearer, as it's very confusing. Otherwise, good job with the project, and good luck if you're polishing it after the jam!
