This is my game "A Conglomerate of Pixels".

You're basically a pixel that runs around bumping into other pixels. The pixels you bump into stick to you and give you additional protection/powers (hence you evolve your pixel).
Attack enemies and other players by shooting them and ramming into them (best only ram into them if you are surrounded by pixels). Don't try pick up a pixel that's connected to an enemy pixel, you'll just hurt yourself :`(

Pixels:
White - Protection\Heavy
Blue - Protection\Speed Boost
Orange- Protection\Directional Shooting

EDIT: Any clump of pixels with a halo surrounding it is either you or an enemy. Enemies are red and the players are either purple or yellow.

There are 4 single player levels and a 2-player vs mode.

Controls:
Player 1 (Purple)- 'W' 'S' 'A' 'D'
Player 2 (Yellow)- Arrow Keys
Press Escape at any time to return to the menu.

This was built entirely in Unity3D and sound was made using http://www.bfxr.net/
