Movement by recoil is a woefully underused game mechanic, so I'm always happy to try new takes on the idea.

As a shooter, this is fairly basic; shoot at enemies, get high score, and don't die. The main difference being in that movement mechanic; your shots are also your only way to move. This means you've gotta think ahead; the recoil from shooting at an enemy could launch you into another, or into a wall.

The core idea is brilliant, but what's missing here is polish and development time; you can tell this is still pretty early in development, the graphics are pretty barebones, and there's only 4 (?) enemy types at the moment.

Probably worth picking up if you want to keep an eye on a new and interesting idea.
