I’m making adjustments and additions to the core gameplay. It’s still running on HedgePhysics, just modified HedgePhysics.
Gameplay additions include:

Boosting

-Boost is limited in this game, much like Unleashed Wii.
-Due to lack of a lives system, Boost directly takes 20 rings per boost rather than using a gauge.
-Each boost lasts 3 seconds but is cancelled out whenever you leave the ground via jumping, falling, or hitting a spring.

Drifting

-While not implemented, drifting is a planned addition.
-Drifting will work much like in the first Sonic Riders, where you slow down enough to make a tight turn and upon releasing the drift you will dash for a minor speed boost.
-Drift bonuses will add to score like in Colors.

Action chains

-Since there is no boost meter, Action Chains will add to your score.
-Unlike Unleashed Wii, dash rings and speedpads will not add to your Action Chain. Speedpads will end your action chain.
-Action chains are counted by homing attacks. For instance, if you attack an enemy and then home in on a spring, you will begin an action chain.

I am currently working on updating this game’s page to reflect the game’s current state and direction.
