Crestfallen Studios

I've played through the game twice, but there's one detail that eludes me: the way to get into the post-show music hall. Is there a way to do this?

Well... You need to do the date sequence then talk to Celestria and Marasha to trigger an event. Go to Celestria's clothes shop, pick up the key there in the room that she takes you. It leads back to the concert hall where theres some extra stuff to do. Tell me if that was helpful.

i didnt see a key in the room when i did it!

It is on the lower level, next to the door. This will help you get the painting you were asking about in the other topic.

Its invisible. Just walk on every square in the room.

There's a small red shine.
