For some reason playback is stopped after round 2 (or more probably nofrounds-1). Need to fix that.
And due to the lower framerate on the device, my collisionroutine misses completely passing through situations, so that will need to be extended with a shell collision routine.
After that it's fiddling with the controls. I've also had a look at adding a menu system with more than a single track, but haven't been succesfull so far.
