A short little piece that puts you in the role of a door (to where, not sure), and gives you choices on who to let pass and who not. That's really it. Your decisions determine which path through the story you take. Currently not a ton of different options, but a few clever ones and some that don't really make a difference which you choose.
If the author chooses to expand this, I think it would have great potential to tell a much more interesting and deep story then it does now. I gave it three stars simply because of the potential and because of the ideas it has generated for myself.
