The most important thing this game layers onto the Sonic the Hedgehog template is versatile movesets for each character that gives huge breath for improvisation and recovery, allowing more room for keeping the flow going as one glides through levels.

The tools each of the four characters are also very different from each other, each resulting in their own style of movement and their own challenges in different levels.

The movesets also result in fun, expressive combat. The game has thirty-two levels and all of them have bosses to fight (though some levels are just boss fights) and some of them are really gratifying to bang one’s head against a few times till finally getting how to read and dodge and counter them.

A few other tweaks from its erinaceous roots like lack of contact damage or knockback help to keep the pace of both the running and fights smooth even if you do fuck up a bit and make the whole thing extremely satisfying.
