I really love the minimalist nature of the game, and it's really clever the way the puzzling works. Although the solutions can be simple at times, that means that you never get so frustrated that you give up, and the parts where you have to be clever just makes it all the more satisfying to complete them.
For those who are having issues on the first level, no, your game's not bugging out, you just can't move soil. This isn't Minecraft. Think laterally.
