@Gfk:
Jealousy is an ugly thing.
Oh, yeah. but I'm not jealousy, because I can do a match-3 game as good as the grey one.
@Grey:
Analyse, duplicate and improve that genre. If it is received well, repeat, adding variation and improvement each time until I get bored or customers/portals stop buying"
that I said, is the only reason to still making the same game.
