This is a great game, it's interesting, the game-play is good, the customization on weapons is the coolest thing ever and I really enjoyed it.
But... The controls are god awful and with so much going on on the tiny screen sometimes you can't really tell what's going on. This was especially annoying on the later levels.
By playing with the default controls my hand cramped up really bad by the third level. This was only alleviated by switching the cursor over to the abxy buttons but you still have to tap on the touch screen to use your powers. In the middle of a fight when you really need to tap the right power and you try to switch from the abxy buttons to where that tiny little slider is, you can probably guess that I've missed more than once and died because of it.... Even with the default controls and using the stylus generally speaking a slider doesn't work out too well.
The game is great, the online is really fun but I'd say this game was made on the wrong system.
P.S. There isn't any real circle pad pro support either, they just say that there is because you can use it instead of the right circle pad to play left-handed.
After 20 years, the series returns in full 3D, thanks to Sakurai. Unlike the previous 2 games, this is not a side scrolling platformer, I don't know what it is actually. It's separated into chapters where you are on an on-rail flight and then a rush to the boss on foot. It acts like a shooter with more focus on weapon types and just bashing enemies. However it is incredibly fun, especially the melee function. This is also the first Kid Icarus to include multiplayer. I'm not gonna explain everything, it's best to play it for yourself and learn to love it on your own. But I will conclude with this, I highly recommend it.
