Not Mother Load
No ending? Really? When I first saw this I thought it was an awesome update to Mother Load. Then I mined EVERY SINGLE ITEM, and realized you couldn't get through the bottom layer.
The graphics were a nice update from Mother Load, and I also liked the fact that you didn't have to fly back the the surface, but I have to say, Mother Load is the better game. At least it has a story and a final goal.
It's a very nice looking game, but compared to its predecessor, it's very lacking. I would suggest you expand it.
