Fixed Some Bugs

Hey everyone. I had a couple of bugs in the demo that I fixed, but forgot to add to the public build, as well as a couple of things that I've added. 

• The portraits are now in the game. 
• Rin's sprite has been updated. 

Bug-fixes

• It is no longer possible to go through the floor when exiting Manami's room. Thanks to Smartie for recreating the bug. 
• You can no longer talk to ghosts. (prompts appearing in the next map with no character attached to them)
• The E and F prompts are now switched to match what button you're actually supposed to press. 
• Talking to Ryo no longer crashes the game.
• It is no longer impossible to leave the library.
