I have it, I love it, I play it a LOT.
I played it obsessively until I mastered all the levels on all the games.
The only complaint I have is that once I did that, and unlocked all the games, and bought all the "prizes" (that help score enough points to get all the levels, plus a new background for each of the games) - and there aren't that many of them - the prize points just keep adding up with nothing to buy them with. So when you complete the first stage of each level & it runs through all the points, it takes a while (I'm over 3,000). I wish it wouldn't do that - or have more "prizes" to buy - even if they just sit in a box somewhere and you never see them.
It's still fun to play - and I like getting better at the hard games and getting better scores. It's just once you make it all the way through all 5, there's nothing else (besides score) to shoot for.
Still, VERY MUCH worth the money!
And I still haven't figured out where/what one of the prizes in the dart/balloon toss is, or why the prize in the shooting gallery is (shooting at the rolling 100 target) is such a great thing...
