I did have a look at it briefly, there are no red hard reset bubbles behind the starting lines on these tracks and in fact there's still white bubbles denoting the road is valid, but you still get reset. There must be something else going on as you can go backwards as much as you want once you're on the stage but as soon as you go backwards cross the start line it'll reset you.
Dune did in fact think of that, if you go even a little backwards beyond the starting line then it resets you right away.
Cause mashing spacebar a million times is bad for your wrist/hand to say the least. Now you can use any sort of macro you prefer to skip dialogue. Not gonna allow any other use of macros or automatic inputs for now.
On the leaderboard just click on the show rules button in the upper right of it. Shows you all the rules for the category and the game as a whole.
