4x4x4: Ruins

@GFJ Let's just say that the intended solution have a multiple path. It doesn't matter which way you choose because both still have the main element, which is the tricks. The main different is the stability of the gameplay. The main path is stable enough to perform the tricks well, while the other path is unstable which can work but mostly will fail. That's why it's still part of the intended solution, but more like an 'alternative' one.

| I thought the other side of the level plays an important role to finish it but the tricks can be performed stably on B's initial position. It's impossible for B to step on a stair block sideways unless he will perform a move that will allow him to "jump" and land on the intended spot. The main trick is unintuitive but a player can come up with it when all other tricks have failed. Tricky level overall.

Honestly I didn't like this one. I solved it via a weird sequence of SSS steps with no much logic.
Anyway, thanks for continuing sharing!
