I think I've come across a bug (on Mac) where interacting with some but not all things on screen stops working, i.e. trying to talk to people on the left side of the screen does nothing (although Poirmento does move to the right location). Is there a way to work around this, or stop it from happening? I only started playing the game yesterday, so I have no idea how rare or common it is yet.
Apart from that though, having a great time!
