Really interesting game. In all bullet hell hames I played there always was that thing where in easy levels player needs to aim at enemies and in hard levels player needs to dodge enimies bullets. But you manage to came up with a game that has PERFECT ballance to it. Player always needs to dodge enemies and aim at them the same amount and i really like how this works in your game. As for suggestions i think the controlls are too floaty and smooth, and of course there is not a lot of content. But this is surely very good idea for a bullet hell game and i liked it a lot.
