I don't understand this game. No idea how I got the elevator to work. I changed the switches afterwards, but the elevator kept working. Confused by the vending machine, which first complained I had no money, and couldn't be interacted with after I found some money.
You created a very nice ambiance, it was quite cool. A reticle would be a nice addition, it is currently hard to tell exactly where you are clicking, and impossible to tell what can be interacted with without running around smashing the left mouse button like an idiot.
