Fist Flier
Fist Flier is a game that is made for and submitted to a One Hour Game Jam with theme Clouds.
Concept
A Fist Man is flying, but very vulnerable to the clouds above and below him. He floats down by default, but holding down left click makes him ascend over time. Fist Man accelerates over time and the passage becomes more narrow as well, but 13 powerups spawn over the first 1000m of the course, making those processes slow down for 5 seconds.
Controls
The only control in this game is left click to ascend.
