You are in a very beautiful art museum, the paintings were so pretty that you had to touch them(even though you're not supposed to) and then, you got teleported to the place the painting is of!! It was like a 3d version of all the art you saw in the museum! I hope you have fun visiting all those places!

A huge thanks goes to @Nols for teaching me how to change the gravity! meaning, when you go into the moon painting, you'll have the low gravity and when you go out, you'll be back to normal. Unfortunately, you can only go to the moon painting once, since there's only one power up and once you use it, it's gone.
