The idea is really clever. It's immediately easy to grasp but there is room for a lot of depth and strategy there because you have to manage your leaps between the leaves to make sure neither leaf grows too quickly.
But yeah it's hard. The speed and inertia on the jump leaves little room for error - can't get past that bit at 30! It would help if you had a little more time and were a bit more manoeuvrable when airborne.
I like the little character in its judo outfit and no one has mentioned the jaunty tune yet. Good stuff.
