It was really nice ! I like these puzzling games. The isometric offers a good challenge.
I'm just a little bit sad I couldn't pass the level 2 because I placed the tiled incorrectly at the end. I even took a screenshot but It didn't works. I supposes it because I could crossed certains blocks or move certains blocks at positions I think I normally could not so the result I see is not the result necessary for finishing the level.
But really great job !
