You know what they say

If it exists...

He is too powerful

I might have to go through again on low difficulty just to know what you're talking about

Yeah idk what to tell you I don't remember that part very well because of how much of a mess that level is

It'll be closed but you can use the button on the left to open it

Pretty straightforward from there this is the only part where I got stuck

I recommend going right after this there's a funny easter egg
