As much as I would love to watch Pewdie play this, I don't think it's polished enough to play.
Here's some bugs and criticism I've got for the game:
I ran into a bug several times where I jumped into the wall by the laudanum and got stuck in there, so you need to fine tune the hitTests with that. This happens from both sides of the wall.
Also bro has a huge hit box and kept getting me through the wall by about 10 or 15 pixels.
The overall controls are really hard to use. There is a huge amount of sliding and drifting going on and it makes it hard to play as a platformer. People who play platformers often praise classics like megaman and castlevania for having "tight" controls, meaning it feels like you have a solid grasp on your character and you can accurately control their movement how you want and need too.
Ok, another big issue, especially with Pewdie. There are no tutorial and we both know Pewdie will be completely stumped unless you make it very obvious as to what does what. He'll overlook the "help" in the menu and complain about not knowing what to do. Even posting the text "S = chair mode" right in front of him is something he might overlook for a while. I actually accidentally figured out chair mode after being killed by ao oni a couple times and kitting random keys. I then lost a lot and went back to look for instructions. I checked the "help" to see if that might be instructions and was right. Problem, it a long manual and he'll likely skip it to save time on making his video. He skips letters all the time, so he'll probably say something like "you guys can pause if you want to read this" and not even realize its the instructions.
I highly suggest polishing it and playtesting the shit out of it, giving it to some friends to test, polish it some more, Then tell Pewdie about it. I'm currently working on a Pewdie game for him too and I'm taking my time. I won't be done with it for several more months and I'm doing everything I can to keep quality of the game as high as I can, I suggest you do the same.
You've got a good base, and I don't want the 2/5 I'm giving you here or anything I'm telling you to discourage you. I just think at the current stage of the games development its somewhat broken and could be a lot better. I've been working with flash since flash 6 I think, and I know its not easy. Take your time, practice and don't give up. And one thing you have the luxury of having is being able to know exactly how Pewdie will react in the game. He's very predictable most of the time and you should use that to your advantage when designing the levels and scares in your game.
Good luck, and I'll be keeping and eye on you to see how you improve.
