I'm sure you've realised this by now, but you are allowed to enhance the orbs to get through the locked doors. I did question that too when I first started the playthrough for the trophy, but then if you weren't allowed to enhance the orbs then you wouldn't be able to finish the game lol.
Also, my first playthrough of this version I did the water puzzle first try, I wasn't really thinking about it. Second time I did forget how I did it and died. Panic makes your brain go to mush.
Yep, haha. I didn't even look at the enhancement menu so when I did I was like "you can upgrade the orbs?"
I managed the trap rooms and water puzzle first try. I just remembered them from back in the day. Funny how memory works huh?
