I stuck. Was neither able to jump, nor to move left. http://oi61.tinypic.com/1t4u4i.jpg Walked right, jumped left and got stuck on the same position. Next time it worked as it should.

Finally the intermediate version :) What is meant by ^x"root-sign"y? I thought that the "x" is the small number on the root but that doesn't work. For example ^2_/1 seriously should be 1 and ^2_/49 is 7. But the answers were wrong.

Thank you for already 7 votes! (And that many although no one saw the increasing of difficulty yet. It does not stay the same for ever. Go for 5 laps and more.) ;)

Thanks :) Nice, I see a 3 there. Probably I should add the highscore table. Btw, my highest on the real Mr Flap is 34, here it is only 14 yet, but didn't play much.
