What a quirky and wonderfully unique little game! It reminded me a little bit of a game I played ages ago called Thomas Was Alone, in a good way!
Basically it's a puzzle platformer game where you can switch between and control various different characters, each with the own specific ability (high jump, fast running, longer jumps, that kind of thing), and your aim is to escape without dying! Well, without too many people dying, at least.
The idea of having to die a few times to learn the ropes really gives the game a lot of replay value, and I got a lovely little feeling of accomplishment when I made it through the level with everybody still in one piece!
If you like games that exercise the ol' brain, I can't recommend this enough! Amazing stuff from everyone that worked on it, hope we get to see some more =)
