I have uploaded v1.1 which should address many of the performance issues you were having. I'd love to hear your updated feedback if you get chance. Thanks
It loads the main menu, and I can see the meteors loading in, but in game the frame rate is really low, I dunno if its because you have a lot of (while / for ) loops running in the background or something to rotate the meteors, best bet is to upload a video of yourself playing it and I'll rate it of the video
