I cant remember the instructions on how to imbue the crossblade with torch fire. I looked at a youtube video and tried to replicate the process shown, but no luck. Did anyone else have trouble with this part their first time through the game?
Honestly, I really want to like this game but sometimes it just seems like there are far too many puzzles.
Try to read instructions carefully :) Anyway, with your crossblade, aim at the torch, press L2 to to lock it, now aim at the bomb, lock the target and use R2 to fire away. Press right analog stick to enter aim mode. Now it can sound complicated, but after you practice it multiple times, you will remember it naturally and it will be easy to pull off.
In some puzzles, you need to bring a fire from torch to another torch. Just aim at the torch with fire and then at the torch without one.
And uh, there are plenty of puzzles in dungeons, but there's plenty of action too, so it won't be one-sided. :)
