Alright, a couple of issues I had in this mod in order of when I experienced them...
1. So, I was really just fucking around, especially when I got to the spots with the steam. "Let's jump over the steam!
" Died of course. Respawn in the cell, go to the other room with the steam. "Let's duck under the steam!
" Died of course. Respawn in the cell... completely unable to move, access inventory and I need to completely quit the custom story. ...And then I need to quit Amnesia because Wake disappeared from the story list.
2. Start game again, go to Wake, and I'm a little more serious now. Thinking I might be able to get across the steam by stacking boxes and crawling over the pipe, I do so. I fall, die, and respawn in the cell. Again completely unable to move, go to inventory, etc. Quit out of the story, Wake is still there, and I start it again.
3. I look around, find the wheel to turn off the steam, pull the left lever first and the reaction I get makes me think it's the wrong order. Okay. Pull the middle one, see that it goes down and I'm glad to finally get the steam in the hallway off. Pull the right one for good measure, get the same reaction as the first, and decide to continue. Go down the hall, try to open the door... locked. Okay, there's a key somewhere... except there isn't really. :| Go back to the levers, try the left, doesn't move, try the right, doesn't move aaaaand I'm stuck.
I take a look at your walkthrough and see what the order is. The way you have the script might not reset in all instances; or at least that's what I would guess. I'm downloading the one that's on MODDB right now if that makes any difference.
I'm sorry I can't continue the mod, kinda want to see what everyone is talking about. I'll try it again when I'm less frustrated. :|
