Oh man, that awful music is gonna be in my head all day! Still, there's an option to turn it off, so I guess I won't knock that against you.
I'd expect something called "Angry Gran Toss" to at least be good for a laugh, but it isn't very funny and certainly isn't a very fun game. Toss games in general feel pointless now that Toss the Turtle has been out forever and clearly proven itself as the best there is, but any other one can still be fun if done well. Angry Gran Toss isn't done well. It's utterly riddled with slowdown, no doubt a result of the unnecessary amount of extras, and even without all the visual choppiness, it's just a sloooooow game. I never felt like I was launching Gran that far at all, even after buying some upgrades, and easily the worst part is how Gran just STOPS DEAD the minute she hits the ground. There's no sense of momentum; she should bounce around for a while, but she just goes splat and does a few half-hearted hops like a fish out of water. Very disappointing.
