The back end of the campaign certainly does feature a lot of identical corridors, truly exciting stuff. Cracking grappling hook, too short by about 1/2.
I found the initial card game too random for my tastes (I don't want to replay a section over and over if I understand what's being asked of me), but let's just say there's plenty more in there to grab your attention.
I don't think I can be trusted about this one. Disregard anything I say since this game pressed itself into my brain while it was still soft and squishy. That said, it's the best puzzle game ever made.
