I'm a fan of the pixel art, and I loved these cute images and movements of the characters. I think the game is very funny, specially because each level is a little diferent, but maybe after playing 10 or 15 could be repetitive for some people. However, that's not really a problem, almost all games are equal in that way.
I think the real problem is the lag of the game, sometimes I get a lot and I can't play, and when it has gone, the minigame has ended, and obviously I lose. Without that, the game is very enjoyable.
