Hello, and welcome to the shmups forum!
You game's artstyle is so pretty and charming. I think it is quite eye-catching.
I checked the twitter page a bit and saw this
boss fight video. I have a few questions/comments :
-Is the player character in the PC version supposed to be mouse-controlled or is the video a mobile build? Touch control is fine for mobile, but you should defintely put digital controls for the PC version. I suppose that from a level design point of view, it can be a bit tricky to have to design patterns as the player speed is fixed with digital controls and rather freeform with touch controls. However, mouse PC shmups are very far from the norm.
-Is the music playing in the background just a random placeholder, or is it still representative of the planned musical atmosphere? I have the feeling it clashes too much with the bright and peppy colors. That's not to say you must have some upbeat music and a contrast between sound and visuals can not be pulled off (see Dangun Feveron for example), but I find such a track more fitting for a visually much darker game. In short, the sound is really metal but the graphics are not.
