I tested it on single player, so I don't know how well it works with twitch.
I like the idea of throwing patterns at the streamer :)
Game is a little difficult due to unusual controls, but after getting used to it I managed to survive for 2 minutes.
It's polished and fun and I didn't notice more than 1 issue: the singleplayer button in main menu is covered by the square and there is no exit button.
