Started the series this year, so have only played the first one. Surprisingly good Sonic clone all things considered. There are a few problems, like the game isn't the most cleanly coded which can make it stutter and some of the powerups are much more useful than others. The story has some... well, it definitely feels like the story of a Sonic OC. There's some charm in that, despite everything. The soundtrack is fantastic, though, and the gameplay is pretty solid.
Whenever I see this game in action, I get that weird impression I get from watching other Adventure-Style sonic fangames, where the character is boost-y and float-y just enough that they can ignore and skip large chunks of the geometry in stages. I'm sure that perhaps the game isn't all much like that in action, but always appeared unappealing and I haven't been able to pull the trigger.
