5x5x5x5

Spoiler

1. The falling trick (aka Tripping on Air)
2. R is B's nemesis in the series, but they'll help each other in this finale.
3. Notice the half metal pillar on the draggable

@chemi Thanks! I was wondering if I made it too tricky, as this series used to be simple

Spoiler

I'd say yes -- the Hot Feet exploit is required (no matter dead or alive), though the intended way is to survive. But then I only realized after uploading the level, that how difficult it might be for B to land safely on the Win (the timing is more demanding than expected -- B is set to reach the staircase, but by autopilot he instead lands on the adjacent stone pillar), so I'm fine with both ways

Step onto the zapper when it is turning around. As soon as he moves by the staircase, tap on it immediately.

Spoiler

The timing is indeed quite demanding (I only realized this after it's uploaded ) and B can sometimes get zapped because the staircase goes downwards. In order to land safely, he must stop at the stone pillar.

A side note: The final staircase goes downwards because I had to prevent it from being accessible using the draggable lift......If I make it upwards instead, it'll go beyond the 5x5x5 dimension

@TR O Nice one I didn't even think of this solution

Spoiler

(I stepped onto the zapper once only)

Tricky one! 625!

I am not sure what was happening at the end - B just died and rolled diagonally to the win. Thanks for sharing your most difficult 5x5x5 remake.
