Yes, this was asked before but we never got any changes, so bringing this concern back. The Hard game mode is supposed to be a challenge, I know. But it's virtually impossible to win. 20 guesses and 16 cards is a big no-no. The best I could do were 11 cards matched, and that was by getting REALLY lucky. So please, increase number to 25 or 30 guesses?

[edit] Apparently is gonna make the changes herself :D

There is a current open topic here about this issue
