Similar experience here, although I don't think I actually succeeded in doing any of them wrong (although that certainly didn't stop me from trying):Some of those final dungeon puzzles had me STUMPED. One of the earlier ones (the shock/frost one on the first floor, I think?) took me easily at least an hour to figure out, which, once I realized the solution I felt sorta dumb, but also not really because they were fuckin hard. I'm pretty certain at least one of them I did "wrong", because there was a bunch of stuff laying around that I didn't even utilize.
For me, the one I spent the most time trying to brute force was the one where the game wants you to shoot an ice disc around a 90 corner by using a charged wave shot to penetrate the wall above it. The other one was the exact one you detail above, which I did eventually figure out how to do correctly:Even 70 hours into this game, I'm apparently not above banging my head against a puzzle for 20 minutes, only to realize that I'm doing things the wrong way. It happened twice in the final dungeon. >_< (The puzzles in this game are aces.)
First, to free the block, you just walk up and knock the bomb south-east with a normal shot, then use a fire shot to send it to the right and break the rocks. Then you solve the rest of the puzzle my moving the teleport block to the far west portal, hitting the bomb to the right with a normal shot so that it lands on the block, and then teleporting the block around so that it's next to rocks when the bomb explodes.
