I picked this up on a whim when the Lunar Pack was on sale, and I've been very pleasantly surprised and pleased with the game. It's a nice little platform-puzzler, especially for the Lunar pack price.
-You like games with very little guidance--there's no tutorial and there are no hints or clues.
-You like games with an atmospheric story rather than a written or spoken dialogue (there are only a few symbols, no text, as far as I've played)
-You like games where you can find your own way
-You like pixel art.
If, on the other hand, you prefer games with lots of hints, levels, and a clear game trajectory, this is probably not a game you'll enjoy.
Small drawbacks: There's no way (that I've discovered) to restart the game if you get stuck in certain areas of the game, other than quitting and restarting the game. This is only a real problem at the beginning, though, before discovering moves like the double jump. As progress in the game is saved, this is only a minor annoyance. Also, occasionally the various filters are a bit much.
