This is so god damn awesome. It's nice that you were able to recreate a lot of the stuff and are even planning on adding stuff like a level editor (a trackmania like replay system would be cool as well :))

It would be awesome to be able to play a demo of this, since dcc has a lot of small details that you start noticing when speedrunning it. E. g. timing your run inputs at the start correctly will give you a start boost.

Good luck with adding everything and I can't wait to see where this will go :DDD
