Do you wanna go fast and compete on aggregate leaderboards so that instead of aiming to be top 10. You can aim for the significantly more reasonable goal of top 99%? Then buy this game.
I think I'm in love.

...Ok so it's early enough in the games life that 99% is still top 3 or whatever for most levels but you get my point. Even if it reaches the time when the top 10 are all near 100% perfect execution. You could still have a not-impossible but still mega challenging goal to aim for without it feeling pointless.
Considering this games main appeal so far is that each level is as much as race against the online ghosts as it is just getting through the level. The fact that it was so well implemented is awesome. You can even set it so that it shows you the ghost of the person 1 rank above you so you can slowly improve and knock them out, without needed to jump straight into crazy launch strats. It's one of the best I've ever seen.

And the game itself handles like a dream. Sure it's obviously intended for going fast (In fact one might say it doesn't control so well if you're slowing down) but you're never wrestling with the controls for anything. Perfectly smooth framerate, alt-tabs without a hitch, and the animation is delightfully simple and appealing.

Great job devs!
