Whilst this game isn't the best complete fan game you can play (even it's own sequel is better) it is still well worth your time.

What I like most about this one is the way where you switch between Sonic and Tails per Zone. This allows for levels that take advantage of Tails abilities as they don't need to accommodate Sonic.

My biggest gripe is that the physics are a little bit off. Most notably when you hit a badniks from below as you will be shot towards the ground suddenly, this was still catching me out at the end of the game.
