Here is my finished game, it is called king karting because the Track is in the shape of a crown.
Blender 2.79 is what is was built in, works in UPBGE 2.5, but had some weird vehicle issues, playable. UPBGE EEVEE crashes for me, with pixel shader on, without it works but no textures show up ingame.
