Not too hard, Not too easy, a rather simple level that requires you to jump from one platform to the other. No need to change gravity. Just use the blocks in front of you to stop and think about where to land.
Instead of heading left, jump onto the right platform that looks like stairs. Jump to the next platform, but on the right side of it. The bonus should be at the very bottom of the next platform. Take one more jump to complete the level, and be sure not to wait too long or you will fall of the edge of the platform.
