I find it incredible when someone leaves a review and the people who made the game leave a nasty reply. Nobody cares if you decided that all the levels are passable. If people can't get past a level, that's it. You cannot argue with them that they can. Considering that you need people to download and spend money on your game, you might try to be a bit less nasty. I was going to try this game, but more I'm deleting it right away.
