Some interesting track shapes you've got going here! I wasn't aware of this online Mario Kart game but it sounds pretty neat! Nice stuff, overall.
I don't know if you want to be very faithful to Mario Kart, but how about making a track that is the city of Splatoon (I forget what the name is)?
iI took me a moment to understand what this thread is about. I have played the first tracks and it is pretty funny, especially the drifting feels good. Is there any way to change the controls? I've been playing on the keyboard and jumping with CTRL and using items with spacebar is a bit awkward.
Perfect job! I used to play Mario Kart and I liked it very much and even once I built tracks for Mario Kart but I don't have it with me, in the SNES console you can also play Super Mario Kart and build tracks for the race!
