Honestly, I'm not too thrilled about this game.
For one thing, the perspective is totally screwy. The shape and angle of the boxes look distorted against the rest of the level. The floor tiles and also square (not rectangular, as a square tilted in 3D space would look). Pushing the boxes across the floor and onto switches, the perspective just seems totally out of whack.
Besides that, the gameplay itself is rather boring, presenting no truly engaging puzzles, just repetition.
