I finished Subsonic with all gold. However what's up with the rankings? World record times are 4 minutes? Is that for Hypersonic? My times are in the 10 minute range for Subsonic.
The random crap with huge setbacks as a result is a bit annoying, I guess without it the game would be over too soon. Still not fun to get hit by a random fire ball in the last lap or bumped off the track by the AI in a turn and go from first to 8th. I guess rubber band AI will never go away. Best to save boost for the last lap, as they'll slingshot past otherwise. I've come in third with much faster times, than when biding my time and going all out in the last lap, placing first with a slower overall time.
Anyway it's smooth, short load times, keeps it fun to try again.
