This took a mechanic I was familiar with, ghosts in racing games, and give it such an unexpected twist. This game might have my favorite interpretation of the theme so far. I liked using my ghosts to unlock shortcuts, and the purple car mechanic lead to some heart-pounding races as I tried to finish a lap to get back to my stash of ghosts.
Speaking of this, I was a bit confused. Do your ghosts reset every time you finish a lap? Or is there some kind of timer?
The ends of races got pretty hard sometimes, as I had no ghosts to work with when trying to outrun the purple car. I got kind of annoying the be on the third lap and resetting back to the beginning. Over the course of the minute it takes to get that far, it's unlikely that I'll be close enough to my ghost to be able to use them against a purple car when they're needed.
One small detail I really appreciated were the two sandbag roundabout on Track 2. It was cool to have the option of charging up nitro, or slowing take to take a sharp corner. I don't think I've seen that kind of layout in a racing game before!
Overall, great game that had me playing for quite a while!
