Gimme Friction Baby is a game written for JayIsGames' Casual Game Design Competition #3, whose theme was Replay.
It's a pure, minimalist piece. There's some austere music; there are a few highly geometric elements, in black and white and pale blue. Even the lettering is a blockish sans-serif.
The gameplay is similarly free of complication. The player fires balls up into the space overhead, where they gradually slow (presumably thanks to stiff air resistance) and then expand to fill as much space as possible until the circumference somewhere touches a wall or another ball. The player doesn't even get to aim the turret, just choose when in the course of its slow arc he wants to fire.
