Good and simple execution of a bullet hell. The gameplay and controls are very easy to understand so you can get started right away. I like that you kept it simple with automatic shooting so the player can focus on dodging.
However as a jam entry I don't see how the game relates to the theme. I'd really enjoy if you add sound next time (even if it's just some simple blips or whatever), it really adds a lot to game feel to get some audio feedback.
Good job on your first short jam & good luck with any future jams you participate in :)
