Love the bloom cubes they make me think of Tron. So for a game idea what about a simple sidescroller. I like that the Tron world was modifiable at will by the programmer and made of bits that could be disassembled and reassembled into new things. So how about a game where the player can brake things down to bits and reshape the world.
Giff to be removed in a week - took hours to make this crappy art lol
