A very well made puzzle-platformer. I was able to figure every puzzle out on my own (with the sole exception of S-ranking the first level, because I didn't know about the out-of-bounds mechanics yet), so if you want a really hand game, this might not be the best choice, but the polish and style will still make it enjoyable regardless of how easy you think it is. The secrets are very old-school and obtuse, so if you aren't into that type of thing, just look those up. Everything else is worth figuring out on your own.
