yeah to get easy money - go to underground boxing, place your bet of $100 first on any side, whatever colour wins, the next one will be the opposite colour and it changes back and forth after each round.
there is a glitch on world 4 where after you defeat the boss, it says bonus round and it pauses at 66% and freezes and you can see that your tail has been detached.
a really unique game, the concept is great but you need to give the character bonuses when they level up and maybe install to slots of potions rather than just one which would help the players a lot
