My old review from 15 years ago was pretty harsh on this level. I still think it's a bit too linear, but it's not terrible. The false routes could definitely use some tightening up.
Agree with Hi19hi19: the false route is much too obviously false, so we don't even try it. As for the correct route, there are sort of 3 "tricks" but the design is so clean that they are easy to spot.
