Inevitably, though, I’ve been having problems with OpenFeint. Yeah, that’s a shocker, I know. It logs me in when I start the game, but then often fails to record high scores and achievements. It’s a real pain, but at least Unify actually has proper local scoreboards, so OpenFeint is just an extra on top of the rest, not a necessity.

It’s a puzzle game where you rotate blocks made up of two coloured squares to make groups of four or more of the same colour, which then disappear. You start with only two colours, then more are added as you move through the levels.

Fairly standard, right?

Well, yes, but the blocks come from the sides, not the top. And two come at once, one from the left, one from the right. You have to use your left thumb to deal with one while your right thumb deals with the other.

It’s not quite as hard as it sounds, while still offering an interesting twist on a standard game type. It also looks really nice, if that matters to you.

But – beware! – there’s a little bit of idiocy that can stop you getting into the game. When you start a game, the loading screen is shown in landscape mode, as the rest of the game is. So you rotate your phone. However, then an OpenFeint splash screen comes up… and doesn’t go away. That’s because the “Continue” button only shows if you’ve kept the iPhone in portrait mode. You don’t want to know how long it took me to figure that one out. Gah. Anyway, once you know, it’s not a problem, but it’s best to be aware of it before you try and play.

That OpenFeint, eh? Seems to be the cause of all my iPhone problems at the moment.
