There's enough new here to make it seem fresh, and those elements that are repetitive are so well executed it's hard to complain about them.

There is no question fans of the first will welcome these new levels and appreciate the super-charged little To Fu. Those looking for a new casual physics puzzler should definitely check this out, too. Just don't expect any surprises and be sure to start in a Zen space before playing – success requires a lot of patience.

The one thing every runner lacks is a way to retaliate. Escape From Doom gives the player that armed advantage.

Halcyon is not truly a must have game despite its intriguing air. Its gameplay does not yield more surprise after repeated play-throughs and so may grow tired quickly, even with the Game Center integration that is new in iOS 4.2. But what is here is fresh, engaging and fiercely challenging; if you're looking for something that's unlike many iPad games out there right now then you should get this one.

It's full of wonderful illustrations, delightfully twisted humor, and just enough nuance to set itself apart from other similar titles. It's totally my new favorite.

This shoot 'em up is devilishly hard.

This matching game takes cues from games like 10000000, tasking players with doing puzzles at a quick pace to complete quests and get rewards.

After 4 years, the latest entry to the Sentinel series is here. It's not quite as wondrous as we hoped but it's till pretty satisfying.

A gem, and a nice change of pace for those who don't think of catapulting birds or slashing ropes as true puzzles.

Fans of shooters looking for a game with high production values and console-quality gameplay scaled down for mobile will love this. Just be aware that it does pale in comparison in terms of complexity to the big-name console titles that it is inspired by.

Despite such signs of a changing market, Beastie Bay might not be the finest of titles from the developer but there’s still satisfaction to be had, once fully understood, although don’t expect to be able to play across multiple devices as there’s still, oddly, no iCloud save support.

It doesn't revolutionize the vertical jumping genre, but that doesn't stop Pocket God: Ooga Jump being pleasant fun.

Homo Machina is a charming and creative adventure game in almost every way, and it’s full of little surprises. The only one of these surprises that isn’t so great is that it all ends too soon. Still though, if you’re looking for something short, sweet, and fun, Homo Machina is hard to pass up.

Is a dungeon crawler that plays itself even worth playing? This game says yes.

With a change of focus from other titles in the Endless Runner genre, Le Vamp is a very enjoyable title all about running away from nasty villagers.

Lunar Racer's fast-paced take on the action racer has a lot going for it, and is definitely worth keeping an eye on in the future. There's plenty of room for more tracks, modes, and vehicles. Noodlecake Studios does not disappoint with this one.

Cannon Cat's well worth a download. Its levels may not involve many different obstacles for our flying feline hero, but its touchscreen-friendly gameplay does a lot well.

Putting a few drops of water into a cup can be unexpectedly entertaining.

It may not be for everyone, but Machines at War 3 is easily one of the smoothest playing RTS experiences that can be had on the iPhone.

Chicken Balls does a great job setting itself apart even though it has some stiff competition from Angry Birds. The graphics and humor give the game a great vibe, and the added gameplay elements really make for a deep experience.

For a simple puzzler that will get players thinking, Oh! Sheep is a nice addition to the genre. The first 15 levels are a generous amount of free levels to get a feel for the game and the $0.99 price tag is worth the total 90 levels. Anyone who enjoyed Spy Mouse and other path-drawing puzzlers should definitely pick this one up.

Vandals may take a lot from the GO games' formula, but there's enough here to show it stands on its own two feet.

This faithful and worthwhile update of the original Double Dragon is an excellent blast from the past.

The co-op is what makes this game stand out; while going solo is fun enough, being able to hop on with a friend to take down some undead is even more exciting.

Chimpact makes me hungry. Mostly for bananas, but also for one more round of play, making it easy to recommend to those who enjoy this type of (one more) iOS monkey business.

At times, Hollywood Monsters might feel a little too zany for its own good. It lacks the polish of something like Broken Sword, but what it does offer is a traditional adventure game, warts and all.

Monsters Ate My Metropolis is a fun if unbalanced card game.

There's not a whole lot about Animal Crossing: Pocket Camp that is surprising. It's a pretty run-of-the-mill, freemium crafting game, but it just so happens to be made by Nintendo, which means it has pretty amazing production values. You'd probably be pretty hard-pressed to find a more pleasant-looking game like this on the App Store, but it shouldn't be too hard to find something a bit more interesting.
