Two things wrong
First, a minor one, the laser isn't actually on the tutorial level. So the arrow seems to just be pointing at empty space.
Second, pausing MUST be a single-click exercise. Having to click twice to pause, especially when the first gate is sometimes very high up, is laborious and makes pausing a very dangerous prospect.
Also, the tutorial and the instructions have different information, specifically about the balls. The pink is either +500 or +1000 depending where you look, and the brown -score ball isn't mentioned in the tutorial.
So yeah, fix those and you'll have a great game.
