Justice has been served! It seems that Dungeon Adventure was removed from the Microsoft store yesterday. Strange that I didn't get any notification from Microsoft... Anyway I want to thank all the people who helped me to spread the word and report this blatant piracy. You all are awesome!
PS: also Knightin'+ is 45% off on Steam and GOG at the moment. Black Friday sale, you know :)
PPS: and don't miss the opportunity to grab a free copy of Knightin'+ this Friday. I'm going to make a little giveaway here on Newgrounds.
