Love the look of this game! minimal graphic design, from the particles to the font for level names. Soundtrack is awesome, but the full games gotta have some other tracks. I wouldn't change the graphics, they feel like something I haven't seen before.(although bearing many similarities to the indie platformer genre) The black and white really makes it stand out from the others. It looks good without being distracting. As you know, level 2-5 was nearly impossible, had to do a slight jump then a full double jump. I love what your doing with the twin characters, seems like you have a lot of experimenting to do with it. To be honest, the levels with two characters are so genius they kinda play down the other parts of the game, so maybe you need distinct worlds. My favorite element is the push-able platforms. Haven't seen that before :). I like the slippery controls, because you have tailored the levels for them. You gotta allow a double-jump without a first jump though.(like dropping of the side of a ledge). Great game, hope the full version reaches the masses.
