Great job so far!
In addition to the other small bugs mentioned in other comments, I found that I was still charged my coin at the first vending machine even though I chose not to buy a drink.
Feels nice and unique. I really like the atmosphere, and I constantly felt the urge to explore and find out more. I was disappointed when I couldn't play any further, but I'm excited for the finished product. Great work so far, and I wish you a speedy development process free from bugs, unless they're the creepy crawly kind.
