Gameplay is very similar to unreleased Sonic X-treme (except fisheуe, of course). You can select one of 4 characters. The main goal is to reach the end of a level, collect bonuses and destroy enemies.
When the level is finished the score will be counted. Each character offers slightly different gameplay. But one thing is still unchanged - you have to beat Dr. Robotnik and foil his evil plans. 7 zones are planned, each containing 3 acts, with the third act as a boss fight.
At the moment two zones are available. Additionally you will be able to play in Special Stages, and some things are unlocked for achievements.
