Oh, boy, are we having another one of those silly old CYOAs that don't really make a lot of sense other than that they're here for the heck of it?
Oh, yes, we are.
So, here's our rather limbless protagonist/sentient keyhole (you're not sure which one) who stands to be standing in some dimly lit room. That weird rectangle under him is probably some sort of text field, most likely for this character's name. Though, given how the box is just sitting there and isn't exactly a suitable size for holding text, that's just a guess you're throwing.
What is this guy's name, anyway?
