I think making the rooms different would help.
My first game, made in scratch while I'm learning to code. Just had fun with it. Use E to interact with doors and boxes, A and D to move. Don't know why but the start is all messed up. If you want a better version go here. This dumb thing kinda refuses to work, so I would suggest going to scratch to play if you want.
