Move block with arrows.
If you have a brilliant idea for a super difficult track, edit the game and create your own tracks and write the game URL in the comments. Edit the game by drawing all the levels you want into the character level and naming the skins only with numbers, then copy all the skins into the character spice and delete everything your main character can touch, do the same with the character you have left (delete everything that is not intended for increased jumps). No level is impossible.
