That' s, uh, really hard!^^' The first pattern is already fast and tricky to avoid. After several tries I'm able to reach the laser part, but I don't last very long.
I really like the fact that the shots are synced with the music though! Almost didn't notice it (the game doesn't let a lot of time to breathe), but when larger patterns appear on percussion and strong chord it really creates a sense of flow. It's not a small feat to make that kind of system work, so congrats!
The scale mechanic could be interesting if the game wasn't so relentlessly difficult. I tried to use it a bit, but eventually realized that I should rather stay at the smallest size and avoid bullets as much as I can.
So yeah, there are cool ideas, but the high difficulty gets in the way. Even though it's expected in a bullet hell to have the screen filled with projectiles, I felt it went to fast to properly navigate through it, and starting from the beginning after only 4 mistakes was too punitive.
