DF? Really?
I'll give you one for making a game that actually works, but otherwise it's a total rip off (as previously noted, numerous times), no original input whatsoever, crappy game mechanics and in all fairness, just enough unbalanced aspects to make the game annoying to play (i.e. useless and little upgrade, long levels that saps all the fun out of it).
How did this manage to get a DF, I have no idea.
