Hi!
I am currently developing a pool game for OUYA and flash (PC/facebook). It is multiplayer only and you can play vs. people in the flash version from your ouya, it's all one userbase.
the physics are very close to real world physics, as pool physics was the topic of my bachelor's thesis. i plan to have a lot of cool functions like minigames and a daily challenge, leaderboards, achievements. you can select a character that represents you to other players, and some can be unlocked.
while the game is 2d, balls are rendered in 3d. the last few days, i have been working on the menues, only got login and character select yet. the game itself is pretty much done. what do you guys think? :)
