It's really hard to not be invested in a story where a Screwdriver was being used as a safety mechanism for a nuclear device

I've played around with a few designs for such, but I've realized that it ended up being more of a 'Puzzle/Strategy' game than horror.
Reinvoking the indie horror genre away from shovelware is not going to be an easy task for any developer :(

You. In.

Oh, wow. Did not expect to ever run into you here-

Eventually though, it will reach the point where anyone who -wants- to leave would have found a way out themselves. Anyone who hasn't dug their way out by then, doesn't want to leave.
Aka, anyone who's paid money to have a mark of "my words are louder"
