I'm sorry I didn't finish your game. I can't stand the bullet heaven genre unless there is a twist to the mechanics that justifies its existence. I just don't think this has much to show in terms of fun ideas except the technical skill to make it.
However, the game works, and I don't want to discourage you from continuing to develop this or other games. So I'll say that its great you made it within the jams time limit, but I'm not a fan.
