You were the first person to have faster times that developers, so it's well deserved. It is happy time for any developer when there is player that enjoys the game to the fullest.
Update: I got all wrs except for one, which I believe is cheated (can you remove it?) Also, am I allowed to give myself unlimited fuel for runs, or are my runs with infinite fuel considered illegitimate? If it's not allowed, I'll try to beat my times legit. Additionally, I gave myself all the pro cars by changing the save file, but I don't think it gives me a competitive advantage.
Progress (default setting runs):
Jumps 2: Beat 2nd place (3rd if you count the 8 second time) but not pb
Hardest map: Beat my pb
Speeeeed: Beat 2nd place but not pb
Obstacles: Beat my pb (by a landslide)
First ever track: Beat 2nd place but not pb
It is possible: Beat 2nd place but not pb
Snake Pass: Beat 2nd place but not pb
Jumps and Jumps: Beat my pb
Ramps with stripes: Beat my pb
Assuming you are Venca, I beat your time on each track with default settings.
