Think Mario RPG, but instead of using the buttons, the Touch Screen.
The plot is a little different this time. Eggman is now a "hero" helping Sonic and his friends stop the Nocturnus, led by Imperator Ix.
The graphics, while somewhat strange, are surprisingly well-working. While characters are the easily most appealing part of the graphics, the fact that the gam actually LOOKS like a Sonic game surprises me. Lately, the games have looked strange. Different from normal Sonic games.
The gameplay is much easier to pick up than Mario PiT. Instead of constant presses of A, B, X, and Y, you use the Touch Screen to either tap a target at the right time, slide it along a red dotted line, keeping the stylus in a circle, or rapidly tapping a circle 6 times. This is easier to do and easier to pick up after being away from it for an amount of time.
While the game may be too short, its humor keeps the light spirit of the game alive, and the fast-paced boss fights remain true to Sonic fashion. Remember, this IS a Sonic game. If you're looking for depth, and a hardcore RPG experience, look for a Tales or Final Fantasy game. But if you want a light experience with fun, like, for example, Pokemon, this is a game to play.
The loss of Wi-Fi is a serious issue. And it've been better to have a wider choice of equipment and attacks. Unfortunately, when I meant light experience, I mean light in almost every sense. Still, the plot is intriguing, the gameplay works glitch-free and fun-packed, and the battles are well-balanced in difficulty. No spikes here.
All in all, the game is good. It's a decent game, but some things that would've been good to add were not added. When you get past that, you finally have a Sonic game in recent years with a story you can follow along with.
