IFComp09 reviews: Spelunker's Quest
Not a whole lot to say about this one. It's short. It's oldschool. You kill things. With weapons. And then take their stuff, because, hey, points. It's stuffed with anachronisms. Eventually you run out of map, and thus escape and win.
My only complaints really involve the transportation between the upper and lower levels; it was not really clear to me that the initial transit was going to be safe (a 20-foot drop onto rock?) and the action required to get back was not obvious. (I think I'd suggest having the object be dirty, since it will already be activated as a side effect of CLEANing it.)
Short, sufficiently diverting, but not really the kind of thing you'd be pressing into the hands of other players.
