If this wasn't part of a game jam, I don't think I would have played it. I don't usually play bullet hell games. However, this was really fun. The controls were smooth, the enemy patterns are varied, and the interaction between your bullets and the enemy bullets is a great touch. The only addition I can really think of is a bit more "juice" when you hit the enemy.
This feels like a game that could see a real release. Thanks for the fun time!
