I didn't think it was a bad game at all. Its like minesweeper, but more interesting. I didn't quite get the kill the monster thing, since they stay where they are, just escape! But I came up with a story in my head hes securing the area for safety.
Its in an alpha stage so I'll give you a higher score because of your potential to add new things hopefully. A different type of monster perhaps. Or a mushrooms that put you to sleep and use up some of your turns. There could be nice things too like say an old campground as a temporary save point on the bigger floors, maybe a detector to find how many spaces to exit or to next good thing (food, ammo). Maybe survivors to rescue?
Anyway, I see potential, and yes, I had played Hunt the Wumpus-- good job
