: there's only one way to find out.. Spoiler It's either you ignore the shortcut and solve it as it should be or take the shortcut.
You put this level in "Exploits" album so I used an exploit - just like @PvB. I tried getting up before the R blocked the way and it didn't happen.
Maybe a touch too early but teacher says, "Every time a slider reaches the ground, a shortcut gets it's wings."
Almost a one tap level because of the shortcut. Otherwise not bad, though it's not the prettiest design.
