I've been on this game for a bit, experimenting with different songs and patterns, until I found a bug with pattern 11. This bug affected both Flower Viewing and Pattern Training (I'm not terrific at bullet heavens, unfortunately) and when I clicked on a difficulty, the song just immediately stopped, and the screen kinda just sat there. I could hover over the difficulties and go back to the main menu, but never further ahead.
As for the game itself, it's very well done. The unique combination of both genres gave a nice welcome for me into the bullet heaven half, making it both calm and chaotic, especially when a sudden shift in tempo came up in the current song, making it even more dastardly.
The characters seemed too static, really. Just a 4-frame loop or something, and it didn't really do much with the physical appeal. However, this IS more about rhythm and dodging, so I'll let the characters slide.
All in all, it's great fun, and I hope you keep it up! 5 5 Fav
