This is a great choice for Classic Sonic fans (in particular Sonic 1 fans) who want an extra challenge. This game remixes the content of Sonic 1 to give the player something that is faster but also more challenging, whilst feeling familiar.

Sonic's moveset in this is interested, he has what you would expect, the spin jump and spin dash. But there are also two unexpected additions, those being the homing attack and light speed dash.

First up the homing attack in this game isn't something to be used wildly, if you do you will likely slam into spikes and projectiles, on top of that there are certain Badniks that are difficult to use it against due to their defenses (those being Catakiller, Yardin and Orbinaut) and there are also inonveniently placed Eggman monitors to make you think about what you are using it on.

Then there is the light speed dash, for the most part this is used to gain speed as the momentum gained from using it is retained as you exit the trail of rings. There are also some shortcuts designed to make use of it.

I would definitely recommend playing the Mega Drive version on this game (v3) over the Mega CD (v4) as this is the more polished version.
