Or - dare I say it - perhaps none of the games you've downloaded from the Android Market have been difficult enough for you. Perhaps you're on the lookout for something a tad more complex - a tad more like this:
Indeed, if a vexing mobile game is what you want, you couldn't do much better than Orbital Defender. Due mostly to the fact that moving around is an automatic ordeal rather than a user-controlled affair, Addictive Zone has a seriously hard-to-play game on its hands - but, at less than $1 for the full version, also one that probably won't break the bank.

Thing is, there's a lot of those raiders, and there's only one of you. As you'll find out after playing the game for, oh, half a minute, that can be quite problematic.
gameplay, and you'd be lost without them - as you well might be if you don't shoot them down while you can (they gradually fade into oblivion if not captured).
To make the game harder still, you can't control how slowly or rapidly you orbit the planet. You can't shoot through it, either; if you attempt to do so, you'll only damage it. Ergo, you must simply keep going 'round and 'round, hopefully managing to kill some enemies along the way.
Again, all this makes for a very difficult game - one so difficult, in fact, that it almost takes away from the app's appeal. Nonetheless, I found it equally difficult to put Orbital Defender down, and its challenging (if occasionally frustrating) nature also means that it'll entertain you for quite some time.
At a very reasonable $0.99 ($0 for the five-level lite version), I wouldn't hesitate to recommend Orbital Defender - just know what you're getting into; otherwise, you might find yourself being regularly and uncharacteristically late for dinner with no one but your phone to blame.
