Quest mode is too hard. FACT. I’ve had a few attempts at it, and I’ve managed a whopping 555 points – which, considering 10th place on the hiscore table is 1000, is pants.
I do well in several of the challenges, and then get one where I completely mess up, and I lose almost all my points. Boo.
If you don’t have a DS, but want to play this ace game, you could always try this link.
Forget that link to Zoo Keeper. Use this instead for a full screen version with no ads. Even better save the .swf file to your hard drive and play from there.
