Fluster is a nice little platformer involving a vacuum cleaner and lots of suck/blow related puzzles. It's only in the alpha stages right now, but it's playable and worth a go.

The art direction is pretty awesome and the puzzles themselves aren't half bad. Note that there isn't any sound as of yet (or at least there wasn't any for me) which takes away from the experience, but all in all this is definitely shaping up to be something brilliant.

Try it out on Schearer and Zielinski's site Another Early Morning.
