Bug: Bonnie's ghost can block you in
After giving Bonnie the flowers, she spends a night with the protagonist. If the player leaves the room and immediately re-enters, Bonnie's sprite will still be in the room. Since she is only supposed to be there for the preceding cutscene, she does not respond to any interactions - but if the player moves a tile down, it will not be possible to leave because Bonnie's sprite is solid and thus she is blocking the door.
Presumably, the flags or variables that prompt Bonnie's sprite to spawn for the cutscene are not properly changed afterward.
