Confusing
Graphics are decent, and very simple, game looks very polished. However it is confusing.
The instruction menu needs more information. I'm not quite sure What exactly the squares are supposed to do to the cube. I tried dragging them over the sides of the cube, but it doesn't appear to do anything.
Also, the simple aesthetic, while initially appealing, gets a little dull over time. Maybe add some backgrounds?
Interesting concept, but needs a little more explanation.
