The presentation is great, but it's very short and very easy. It's far from the best value I've gotten.
For the tiny amount of money I've spent on it, I'm happy. But by all means recommend some more titles. :)
Ridiculous Fishing was heavily recommended in another thread about mobile gaming recently, and I have to say it really lived up to the HN hype.
Crashlands! An action adventure game with a crafting component that's fun even for people who don't like crafting games - you have an infinite auto-managed inventory that just gets out of your way - with a funny, quirky storyline and easily over 50 hours of gameplay, all for $5 (on mobile, or $15 on Steam). Oh, and there's cross-platform saves so you can spend $20 to get the game on both platforms and switch back and forth on your same saved game at your leisure! (I'm a big fan of Crashlands, as you can see.)
