It’s a challenging title at times and some puzzles can leave you guessing for a while.
That goes even more so for those who want to get all the achievements in the game.
There are 21 to collect, with eight of them being awarded to those who can complete each chapter.

Theportal on the tall white wallshouldsend you to the middle platformand thenonto the exit rail walkway.
