So it has to do with refresh rates. I have a patch ready but am waiting on a support ticket. If you can set your monitor refresh rate to like 60hz and try again you should be able to get past that part.
I changed the refresh rate to 60 now I am stuck here19 days ago(+1)
The timing is pretty tight.. I've always had a hard time tuning difficulty for jam games! Something that might help is you can use the moving platforms at the start to get a jump boost if you time it right, and get a little ahead of the track.
