I'm trying to make a cool kids' version of hero beta mode so I changed some values:
-minimum speed, from 0.1 to 0.5
-maximum speed, from 2.7 to 7.5
-traffic compression, from 0.6 to 0.7
-changed some of the scoring values so that it gives better bonuses in the end

I thought changing the speed a little wouldn't really mess up the track creation but I was wrong. Basically, blocks here only spawn on red areas of the song so there's big empty spaces at the beginning and end of each track, and sometimes there's blocks that spawn besides a PB which means you lose your combo if you try to get the PB, or lose a bunch of points if you wanna save your combo...

Any thoughts on how to fix these problems?
