To offer a little less snark and more directly demonstrate for those having a hard time seeing only dumb minigame puzzles. Focus on the segment starting at 0:22 - 0:50

Besides the grid puzzles, which from the few variations we have seen have already shown loads of variance, we see in this short segment:
- Segmented bridge mechanic tied to grid puzzles
- Grid segments being completed as you walk on the glass tiles (it is quick but watch the green grid puzzle through the doorway)
- Maze with sliding walls (Maze is grid shaped from a birds eye view)
- Water lowering, boat door opening, boat ride! (This is incredibly Riven)
- Turning on Lazers to point at the central mountain.
That isn't even getting into some of the spoilery speculation that people have already started working out. This is just a short 25 second montage in the trailer for a game with 600+ puzzles in development more than 5 years by the dude who made Braid, who has proven he has solid puzzle design and complexity pacing skills, and knows when a mechanic has worn out its welcome.
If you think it is going to be 25 hours of
boring sliding puzzles equivalency then you haven't been paying attention.
