OMG!!! I fully support a text horror video game! I have to say I nearly lost my shit when you mentioned Lemmings! That was one of my favs as a kid.
If there is one thing I like about survival-horror video games, it's the crafting of the atmosphere and creating cause and effect that literally haunts you throughout the game. The scariest games were also the ones where the protagonist could not fight back against any enemies.
Have fun designing this game I think it will be interesting to see what you come up with! Godspeed!!!
