Really difficult...
I couldn't find the last two differences on the first level. I'm such a noob lol.
But...I dunno if you're aware of this, or if it's just me, but there's a major problem with the original, 5 Differences. Everytime I load it up, some of the differences on the first level are already fixed, so I can't click on them to 'correct' them. This means it's practically impossible to play the game. However, judging by the reviews, I seem to be the only one encountering this problem...
I dunno if this game has the same problem...doesn't look like it...
Very well done. Only 7/10 because of the difficulty and the problems with the first one.
