The visuals and audio were good, and the concept was creative. You took the spinning theme and took it very literally by spinning a ball. Everything worked well, and the controls were consistent, but it might have been my mouse. I found it infuriating on the more difficult levels. Not to say it's bad, it is very well built, but I did find it very difficult, so if you were going for difficult, then you did a great job.
Nice work!!!
