It has been a while, but I've played a good number of iOS games over the past few months, so I wanted to get back here and update/add stuff to my original post.
Zane wrote:Monument Valley - Easily the best game I've played on iOS yet. It, and its expansion, are worth every penny. Watercolor Escher painting meets a strange ICO-like feeling of isolation and exploration. Loved every damn minute of this game.
VVVVVV - Absolutely ridiculous. Metroid-influenced exploration blended with Atari style graphics, Super Meat Boy-esque rooms, and one of the best chiptune soundtracks I've heard in years. The add-on (Gravitron) is also fun for a few minutes of casual fun here and there.
Both still hold true. I haven't gone back and done any full replays, but I will at some point. Great games! I've also played a ton of crap over the past few months, but I'll save the trouble of bringing those up.
#sworcery - A real treat, and absolutely worth the price of admission ($2.99 for iPhone, $4.99 for hi-res iPad). The soundtrac still haunts, and there's even a rando arrange album with a few very noticeable names on there. Point-and-click style adventure that feels a bit like a platformer, a bit like a Zelda-type game, and a bit like a weird dream you experience during one of those moments when you accidentally fall asleep on the couch and wake up like, wait, what was that dream about? So good.
Bastion - This was a cool experience that got a little long in the tooth toward the last third of the game or so, but was still very much worth it (and with NG+ worth a replay). The way the world builds itself as you explore and the constant narration that reflects the in-game events really drive the story and make it feel really interactive. Gotta mention the notable soundtrack, too. I used the touch controls since it seemed easier for the iPhone 5, but you can use more traditional style flatpad controls if that works for you.
EDIT: just finished round 2 of Bastion, and loved it way more than the first time around. NG+ plus infinite lives plus awesome, upgraded weapons? Why, yes. Also, the tunes are so damn good.
Dead Space - A watered down experience compared to the console game, but I was surprised by how well it was done and how well the controls work. Not a very long experience, but it's creepy, and the way the balance of combat and exploration is structured keeps things from being overwhelming or unfair since you don't have the luxury of a full controller.
Goblin Sword - MAN. Goblin Sword! This is like a little nugget of SNES beauty squeezed onto iOS. At first the levels felt repetitive (each level within their respective areas has the same tileset and BGM), but this game is so damn fun. Challenging, too! The levels seem to be just long enough, and the challenges - finding three gems in each level, as well as two treasures that contain either money or new equipment/armor - are enough to keep you guessing, but aren't so hard that you'll be throwing your iOS device out of frustration. I've been playing this game for about two months now, and am still unlocking new things. The dev updated the game a month or so ago with 16 new levels - for free! Well worth it.
Kero Blaster - Another great retro-style platformer, with a bit of a Contra/shooter type of weapons upgrade system. I bombed through this in about two and a half hours, but loved it and will absolutely play it again. $4.99 is steep for such a short experience, but the quality is top notch. Another game that's just challenging enough, although you do have total control on the upgrading and progression of your weapons. Need more health? Buy another heart from the store. Want to upgrade your laser instead of your bubble gun? Get it done, son.
Rico - I'm only about 10 minutes into this, but I love it. Old-school platforming with awesome music. Can't wait to dig into this one.
Traps and Gemstones - Didn't expect too much from this, but it's a fun Metrovania style game that has you as an Indiana Jones type dude exploring a pyramid to find 25 lost relics that need to be restored. As the game progresses you get new items and skills that open up another chamber or two of the pyramid, and the next thing you know you've spent three hours collecting gems and solving puzzles. The art style looks campy, and sometimes it's hard to remember where you've been because the pyramid chambers look similar, but there is an in-game map that has little dots on rooms either where you can reach the relic, or where there's a pedestal that will allow you restore one of the relics you have. Like Kero Blaster, $4.99 is a bit much, but this is a game I'll easily play one or two more times, so I'll get my money's worth.
