This games Graphics, and Story line are very nice, I give them an 8.
The downfall to the game is the seriously complex control scheme and requirement to have 3 hands at once. Controlling Pit's moves is simple with the stick, this is all they should have done. But instead, the controls to aim your weapon are done by the touch screen, mind you, you still need another had to fire your weapon while trying to Aim, Dodge, and Move all at once.
The game's design is fun. There are tons of different weapons you can choose from including a sort of crafting of weapons to create better ones. You also get rewarded for playing on higher difficulties.
However, this game was nearly unplayable on my 3DS XL. You have to move your character with the left joystick and shoot with the left bumper. You then aim with the stylus. This means that you are holding the weight of your 3DS (not saying the 3DS is heavy) with one hand which puts a serious strain on your hand after awhile as you try to move and fire at the same time. Unless you can find a good way to prop your 3DS on something to support it (I couldn't), then I think you'll end up just as frustrated as I was.
Despite the wonky controls, the air levels do work decent. However, the game really falls flat on the ground levels. Here you have to turn your character by swiping your stylus across the screen and then aiming agin by tapping your stylus. This combo of holding the system, moving (and dodging), and shooting with the left hand and then attempting to aim and turn with the right hand leads to frustration and fatigue issues. The game requires a pretty high level of precision, on the higher difficulties, that just ends up being painful (literally) and tedious.
