Looks good so far.
A bug occurs once Britney tries to walk through the portal and gets teleported to the mushroom. Once you talk to the gnome again, she'll start walking in random directions once you click anywhere and even clips through the boulders and walls in the area. You can still somewhat guide her if you keep clicking where you want her to go and she'll start zig-zagging towards the location, but you really got to fight her on it.
Otherwise I'm really interested to see where this one goes.
