This game is very amusing. You will kill a hundred of different monsters by a wealth of ways. OK, maybe a lillte "bloody" for some gamers. You can really enjoy yourself by playing this crazy devil rabbit. Don't worry about the achievements, because they are neither missable nor demanding your micro-operations. The single tough one is about a slot machine, on which you will maybe spend around one hour by pressing "start" (E on the keyboard). So if you don't want to waste your time but you indeed want this last achievement, you may need a automatic clicker.
If let me to score this game, I will give more than 90/100.
