I picked up the Ultra Galaxy pinball game (whatever the exact name of it is). It's a free download, but only about 30 seconds into playing a game, it will prompt you to make an in-app purchase of the full version ($2.99). I find this kind of annoying because I would have just bought the full version to begin with, but they only have the free version available and make you do it this way.
Anyway, as a pinball game, calling it average might even be a little generous. It's okay. Not as good as The Deep or something by any means. The table is pretty basic and you can't change the view at all. What's weirder is that you are stuck in landscape view, so everything is kind of smooshed down in perspective and you can never get a good look at the rear of the table.
But
It's the only game on the app store with an Ultraman theme, it's full of Ultraman sound effects, pictures, etc. So I would have bought it regardless. And I would not say it is without fun. It's average. And if someone is an Ultraman fan, add half a point to whatever score I realize I didn't give.
