I tried to beat the game without running, level 1 is easy if you jump after walking off the edge, I beat level 2 by pushing the tall block against the wall, going under it and fiddling with it until it laying on the slope so I could jump across, level 3 is easy if you take the back way, levels 4 and 5 I could not beat as their 1st and 2nd jumps respectively were to far. fun time
