I know how much time it costs to reach the playable state. See here many stairs I had to step up myself. This is said by an aged father of three, who loves to see young people experiment and hope, they do so much later in life. Go on and do it better.
Without help screen I do not know how to play it,so I cannot build an opinion about the hidden logics.
Very professional, but much too fast to play with real fun. The idea of making the action screen horizontal is good, but it shrinks the free room for the player to react and mankind is more used to expect a down falling ball. The math is on very high level. Congratulation.
Only some critics: the reflexion of the ball seems not to be exact or "float" and a fullscreen mode would be better. But a nice work.
Perfect! Perfect! Perfect! It is worth to sell it, what the programmer is already doing. A "floating point minus" is the music, I could imagine something that children (and big children) would like to here.
