It was a nice game.
Nothing awe-inspiring, but it definitely was a pretty good first jam entry.
The music fits. It was a good choice, and it helps with concentration.
The concept is simple enough and easily understandable. Though it is almost impossible to plan the route before starting the level, since you can't easily discern in which direction the boxes will move.
The visuals are definitely its weakest aspect at the moment. But they convey most of the necessary information. Meaning: they work, but could sure use some improvements.
