That's great work there! It is polished really well. It was really addictive to play and level designs are good. But there are few issues:
At start while platforms bouncing I think it's better to lock the controls. I tend to play immediately after re-spawn and it causes unpredictable moves.
Platforms rotation delay is too long for me. It could be better with a little less delay time.
And lastly ball control was very sensitive for me.
These are my very personal opinion. I really liked the game, good job!
