This Is Circle Jam!!
Circle Jam is a jam for people with no time and no artistic talent, the only requirements? Make a 2D game in 1 hour using only a circle sprite.

An extra half hour is given for brainstorming, building and submitting, feel free to think about what you want to make, research techniques and get your circle ready before the jam, but your final submission should only contain code you have written during the 1 hour period. 

Feel free to collaborate with as many people as you like
