Cool graphic style and I respect the work that's gone into it. Projectiles in the game are a bit overly dense but I could see it appealing to bullet-hell enthusiasts
I have to say though, something went very badly wrong with the SFX in the tutorial. I fired my lazer and I believe an SFX trigger endlessly retriggered and had an additive effect on the audio. In other words, I was deafened. Quite unpleasant and it's the kind of thing I really wish would have been fully ironed out; obviously not intentional, but I was hurt, and I can imagine other people being hurt by it.
Sorry about the kinda intense comment, but I figured it was worth mentioning. It's definitely a good game jam effort overall
