2/5 not to great, why even add dwarf if there isn't a story line? This isn't very fun, the +1 min is big problem, it needs to add different times depending on the level.
the time limit just makes it less fun, because you feel rushed, not the fun that real game is, where you feel the nice glow of a job well done, the only reason to play this would be to get badges, even then, it wouldn't be fun, it'd be work
like the game but I found one glitch, when you die and chose to continue, you lose the ability to pause open invetory, or switch weapons. I dont know why but 5/5 other than that
