What is this color thing you speak of? Right now the game is at the tech demo stage. I do have ideas for progression but they are unlikely to happen unless I find a sound person who wants to give this some love. Controller rumble is currently broken for me and not an option until I figure it out again. Wind sounds for speed are there but get lost in the mix. Success sound is such a good and obvious idea that I'm almost embarrassed I didn't do it and hadn't thought of it until just now XD
Thanks for playing and commenting.
