e7 is a moody little Flash game that I call a platformer in the tags above, but if it is one, it's an unusual one. You play a little half-disc in a blue-and-black landscape in a sidescrolling view, and your objective is to get to the end of the level, which in typical sidescroller fashion is always to your right. The ground level deforms oddly as you move, which you do with left-and-right arrows; and while you cannot jump in the conventional platformer sense, you can (in most locations) create a pit where you are located by pressing down-arrow, then release the key to bounce yourself upwards as the terrain recoils.
There's a physics element to this -- direction of motion is important, and you are subject to gravity in the air -- and it is a nice, almost floating feel.
Enemies of a number of types can be defeated by bouncing into them or falling atop, but can do damage to you (a variety of attack patterns); it is not a particulary difficult game to play through, but the novelty of the physics and control scheme makes it feel very different from a conventional platformer.
The ending is, like the palette and soundscape of the game, somber and downbeat, but it feels fitting in context.
e7 is a 2011 IGF Student Showcase finalist.
