I loved that movie, but the only similarities are the fog and the supermarket. The background and overarching story are completely different. I just wanted a closed-environment setup with strangers—and it seemed like a solid idea. A supermarket works perfectly because it’s packed with stuff, which lets me create all kinds of scenarios for an adult game.

I recommend you give it a try. I have quite a few other ideas for the future, which include various locations. You'll see then that it's completely different.
Thank you for your interest in my game.
