there seems to be only like 1 choice you make in this game and it could hardly be called a puzzle. you did make a game about finding keys but you just did the most annoying part of it instead of making it interesting, check every locker until you find the key, check every locker to find the key, check every locker until you find the key... ok now you can make one choice and win?
the game runs fine except for a spot the wall meshes clip through each other in a spot. it would be nice for there to be an end instead of just the alien screams when you are close to it.
its fine but there would need to be a lot built off it to be interesting, you could have used the moving things mechanic in more places for example to let the player do more things.
