While mooching the official site the other day I noticed that they have a ZT2 mobile phone Java Game out now.
Apparently if you complete the challenges on it you get free new content for you actual ZT2 game
So I downloaded it.
And have yet to play it (I'm just slow like that sometimes).
What I wanted to know was has anyone out there played it yet?
What did you think of it?
Have you unlocked the hidden content (and is it worth the effort?).

yes and yes lol

the hiden content is an asiatic black bear for the zt2 game you can downlaod and install it into the game - but beware if you do get it people want this bear very much and they will ask you for it - we even had people at za asking for someone to upload it but its ILLEGAL to share the file with anyone unfortunately.

Ah!
That's cool to know.
The interface on this thing is driving me insane (well, insane-er...).
I took a photo of a tiger earlier and it gave me a code for this pretty picture...

poor okapi!!!
