How do you finish level 21 in run 2

Level 21 is quite easy. There are little holes that you jump through and I bet it's the fourth hole you get stuck at. Thee hole isn't really a hole; it's a long brick with a cube diagonal of it. To get past that you have to have you person run to the edge of the block that you're running on and the jump (with the space bar). Hold the space and at the right time, hold the right button. If you're lucky, you'll land on the next block/platform. The rest is the same as before: Just jump through the holes.
