Well it seems to run fine for me. Speed is good and controls seem to be adequate, although I only played for a few minutes.

I did have a problem running it though, the shortcut installed doesn't work for me. The window just pops up and disappears real quick with no error. Same when run from the console. Works fine when run from the console under root. Hopefully that can be fixed soon, other than that minor issue (could be show stopper for some though) great game!
