Thanks for your detailed feedback! I am currently adding a temporary solution to almost all the points you mentioned in the next update so players cannot exploit by opening and closing locker as the locker door will be blocked if girl is standing right in front of the player while player is in the locker. yes the game already has a planned story and will be implemented in future to add a proper understanding of the background story of the characters and will have multiple endings based on how player interact with AI and the puzzles.
