Very enjoyable on the DS.
I've only played it on the PC, PS3 and DS, so I can't compare it to other versions out there.
One thing I wasn't crazy about on the PS3 was the control, I found you can lose track of where your cursor was but that's not the case with the DS as the touchscreen is just perfect for this game.
The mini games aren't available right away and you have to play the game to unlock them but that's not a big deal. If everything was open at the start, you'd probably get bored of the game quicker.
Graphics look nice. Never really experience any slow downs. Even when things get hectic, like during the last wave of zombie attack, game ran fine.
I paid around $12.00 for this game and if even if I'd have paid $20.00, I think it would have been worth it.
Certainly one of the more fun games in my DS collection.
