I liked it. I'm familiar with lightbulb-switching games. Something like that probably already exists in 2D. Still, I think your game is original and perfect for this jam.
Although the controls really irritated me. Instead of focusing on which button to press, you have to fiddle with the cube's rotation.
I recommend adding a menu with the ability to invert the axis movement.
The cube sometimes continues to spin for some reason after you let go.
Perhaps you shouldn't lock the rotation range.
I think level 19 is weak. The four buttons are just dead weight—they never change color.
I'll stop at level 20 for now.
