Quiet a fun game. I think some improvments would be the ability to remove platforms and a quick reset button. And while the randomly generated levels worked quite well (except when the white dot was already on the green on and i won instantly) I think some created on to get to learn the game would be great.
I found one weird bug I couldn't reproduce. I gave the ball a lot of momentum and then it flew of the screen without it losing me a live for touching a red wall. Had to wait till the timer runs out to start again.
