Such a beautiful game! But I think there are some things that can be changed a little bit.
Dash mechanic seems little stiff and for me is a little too short. Especially when dashing upwards. Maybe the idea was not to dash vertically through platforms and I understand that but for projectiles it's too short. Another thing is the lack of grace period after being hit. Most times when Tiana boss (i hope I got i right) does a bullet hell attack 5 frames of being invulnerable after being hit would be enough make this attack not frustrating. But overall it's solid and juicy in some situations :)
