I didn't get into the main mechanic of the game sadly, the whole dash through projectiles of your colour thing would work for me if you could manually change your colour not just by dash, but also on the key bind or something? Now if you don't play perfectly, you just wasting too much time on the state change, so the pacing of the game suffers massively and ruins all the fun.
The second giant problem for me is the dash in the direction of the character look, not the coursor, it's really hurting the whole bullethell gameplay a lot.
But the movesets are nice and with a little tightening up and polishing it would be a great game with cool ideas! So best of luck!
