Anyways, Nano Assault is an amazing game. I've spent the last four hours playing it and I love its excitement and challenge. The stages are varied and the graphics are some of the best I've seen on the 3DS. The audio is the standout part, with a fantastic electronic soundtrack and some sweet sound effects. The 3D effect is great, because in this game it makes the levels feel way more expansive and the level of depth is impressive. Hell, what surprised me the most is that the game actually uses the 3DS's tilt controls (Which are good btw)!
What makes this game a winner is that it's challenging (never cheap though), your secondary weapons rock, You can change the direction of your projectiles, The Arcade Mode, you can buy new weapons, music, and nanopedia objects, and the stages are short but satisfying.
Overall about 4 hours into the game and I love it. Anyone else?
