Happy Hover

Done. This one requires some precision in timing as B would stop hovering once it goes slightly outside of the grass. Sometimes you just have to go back a bit to fine-tune B at a corner for the next glide. Only move in a straight line, one corner at a time. Tap outside the world (white blank area) at the moment B arrives at each corner so that it won't leave the grass track.

I also just tested and solved this card on my 6-year old iPod touch. Everything worked fine for this large level, with only slightly decreased frame rates while rotating the camera (which is quite impressive for such an outdated device), and only occasionally B did fall off the grass once or twice because of an unresponsive tap when I was going to stop him. I still managed to hit the goal on my 3rd attempt

I did have that burning sensation on the iPod's stainless steel backplate though
