There were a lot of frustrations to be had in old Sierra adventure games, but one of the worst was the way the games always made you traverse treacherous stairs, with one wrong keypress killing you instantly. So, yeah, here's a game just about that.
It's called Stair Quest, and it's a painstaking recreation of the look, feel and sound of old Sierra adventures, only it's almost entirely about walking around and inching your way across treacherous staircases (though yes, there is also text entry in the game).
Stair Quest was originally made for Adventure Jam 2016, but this version has been cleaned up a little and had some extra stages added.
If you want to try it out (or at least listen to the very faithful soundtrack) you can play it for free here.
