I spent a good five minutes routing out the entire path for the final level (after accidentally hitting x the first time I beat the game) just to realize that the character physically can't move to the right there. If anyone's curious, the move sequence is as follows: L L L L L L L L D D R (First block in place) D D R R R R R R R D D D L L U U D D R R U U U L L L L L L L U L D R D D D L L L U U R R L L D D R R R U U U U (Second block in place) D R R R R R D D L U R U L L L L L U L D R D D D L L L U U R R L L D D R R R U U U L U R (Third block in place) D R R R R R R R D L L D L U R U L L L L L U L D R D D D L L L U U R R L L D D R R R U U U (Final block in place)
I'm not entirely sure if this would work, but I believe it would.
Actually, I'm gonna recreate this level and see if it does. It's gonna drive me insane not knowing for sure if it does work or not.
Edit: It does in fact work. At least it works if you exclude the fact that the character can't move right.
