Wait what? I've never seen this happen. In fact, I'm certain it's not true, because you get three hints for each emerald shard that cycle in the pause menu and go away once you've found it. That said, I'm calling it now: You're gonna ragequit at Mad Space. Alright, I admit I was wrong about that, but it doesn't matter because I just discovered that this game has a Kart-racing minigame. It's pretty bad because it just consists of a bunch of Sonic characters in the same kart with different colors driving down a generic looking road that was recycled from one of Tails' levels, your worst obstacle being the game's turning controls. What was this game trying to be? Developers can't have fun and add a side-gamemode? The map isn't recycled from the Tails Level. All 3 kart-racing maps are originals (albeit can be bad unless you know how to drift). You've still got the Rouge driving level as well.
