Hey, I was playing this game after looking for versions of Qix. The sphere surface was a lot of fun. I wanted to mention that I noticed that hitting 'x' ends the game. I am not sure if that is intentional, but I accidently hit it when using the controls.
Oh... I forgot to take it out, it was for testing purposes :D
Thanks for playing the game, quix it's something I get back from time to time as a simple concept to build on, for fun (working right now on a version where you tilt and turn the phone to direct the player). Glad you liked the spherical one!
