Thanks ! I'm happy you like it. :)
I also have to point this out, i just found a bug where you can delete walls by using the gray player things and the pushable objects. you basically have both go into a parallel universe (the normal player stays) and pushing the object into a wall then getting the player into a parallel universe deletes the wall. similarly, putting the gray player on a parallel universe and putting them into one of the walls that would stop the normal player while hes in the normal universe, and having the player go to the universe the gray one is in, the gray player is deleted. the first one is the major one as it makes levels easily cheesable so i had to bring this up to you so you could fix it.
