So close!

@Don G Rowe - I think the creator intended the player to cross only by using the lower level of sliders, hence no exploits required/desired.

A rather simplistic ability level that those looking for less of a challenge may enjoy more. The reason that others might find that you can cheat on this level is due to B's path planning algorithm that we call Autopilot. If one taps only the grass blocks then B will happily jump down and/or climb back up from the water. In fact B can overcome any one block height obstacles this way. In order to avoid players cheating using such an exploit you'd have to build the walls two blocks high. Nice idea for a level though that I'm going to tag 4kids. Thanks for sharing!

Thanks for the feedback guys. I've removed the 4kids tag. (@delator77 @Don G Rowe )
