Blossom

WASD/arrow keys to move and j/k to rotate counterclockwise/clockwise. P for pause/resume game and Esc for quit.

You need to touch various squares. Different squares have different effects, including changing the scale of your squares and adding a new one. 

(You need to touch all moving squares to generate a new group of squares）

I see each square as a petal. So,

may your flowers blossom.
