An amazing Sonic fan game that is so high in quality that it fits in perfectly with the classic trilogy as a follow up to Sonic 3.

This game has some pretty cool improvements over Sonic 3 that pushes the classic formula forwards. First of all the concept of having the player switch between Sonic and Tails to make use of both movesets feels like the logical next step with that pairing.

This game takes the environmental storytelling of Sonic 3 to the next level by making Zone transitions seamless, making it even more obvious how all the stages fit together.

One feature I did like is that when playing as Knuckles you can now glide out of a roll if launched into the air from a ramp or by rolling off a ledge, increasing the possibilities for Knuckles to traverse the levels.
