Great game, small improvement needed.

The scroll function (menu, switch between levels) doesn’t work, one has to click and swipe…
Maybe it would be nice to let the difficulty progress a bit slower, but I guess that is a personal preference. As would be a change between dark en light backgrounds.
What would totally rock the game is to tune the music 100% to the positional changes in the game. This would totally kick it into the ZONE.
For the rest, great game.
