I personally don't know how on earth it should be possible to finish this level with just 2 jumps to get a highscore of 98, but I congratulate you nevertheless.
Yeah, the checkpoint in the 21 is VERY badly placed, it shoots you back between 19 and 20 everytime when you jump from there. It should be placed on top of the 2 from the 21, not in between the two numbers.
