I think it was something like 8$, and yes you can try it if you want!! :)
But I prefer the demo I had than the game I got :P
But my ipod is dead now so I cannot told you which game it was :/
I feel like I need to at least give the game a shot. My fandom has no bounds for that game and it would only be like, $5 give or take - even if it was crappy I feel like you would be getting your money's worth.
Bad haha, actually there was 2 versions, I had a demo of one who was very nice but I ended up buying one I hated XD
You have to move the Ipod for moving the Katamari...
