Whoa, this game is cool as hell! It's only $5, and has around 150 levels. I'm just about halfway through it, and I love it so far. It's a puzzle platformer where you can create platforms out of your body. You can make Tetris shapes and more with the blocks you... excrete from your body. You can use them to make platforms, push switches, or zip around to areas you couldn't normally jump to. The difficulty has a slow ramp, but many of the puzzles require some interesting solutions, especially for the collectibles. Well worth $5, I'd say.

Is anyone else playing this?

It's okay so far (I'm up to World 5). I think the interface and controls could be better. Basically, it feels a lot like Blocks that Matter, except not quite as good.

Great game to pick up and waste a few minutes with. Not particularly challenging (yet), but it sure is relaxing.

Definitely lots of fun. There are some cool challenges near the end (I haven't done everything yet either). They are pretty easygoing with the challenge collectibles, as nearly none of them require you to be particularly efficient (they will disappear after creating a specified number of blocks but that limit is very generous in the lion's share of the game). Basically you'll be "perfect-clearing" every level. I was pleasantly surprised at how many levels and mechanics they threw in though. For $5 it's hard to not recommend it.

@quantris: The levels that unlock after the ending are, by far, the best parts of the game.

Agreed, just finished them. There were definitely some that stymied me for a good 10ish minutes before I figured out a viable approach. Also one that I did with 0 blocks (sadly nothing special happened).

I still have a bunch of the challenge levels (score / time) that I haven't tried but so far those are a bit less interesting to me.

But yeah, they definitely found some interesting stuff to do with a fairly simple mechanic. Hope there's a sequel (or even better, a pseudo-sequel with a different mechanic but similar "feel") cause I definitely enjoyed this one thoroughly.
