The menu looks very good and the graphics and the sounds/music are nice. However for me the game is just too hard. The holes are placed too close too each other, and the controls feel a bit unresponsive, probably because the you first turn the playfield, and then the ball has to react to that so I kind of feels like ice in platformers. Also, at first it isn't really clear that the purple circles were holes.
I make the game a bit easier and if possible make the controls more responsive, and it would be cool to play on mobile with tilt controls. Kind of like those wood boxes with a little metal ball in it where you have to avoid the holes and get to the end I used to play as a kid, but on mobile.
