My thoughts on the game:It's fun, I had a blast.
The graphics are clear, the gameplay is simple yet effective and the puzzles really get you thinking.
My only gripe is with the fake walls, cause it feels like the puzzles become more trivial afterwards. Clearing the fake walls becomes the main objective and moving the boxes in their places becomes a cake walk, which in my opinion takes away from the fun of trying to figure out how to move the boxes.
