What IDK how but i was able to enter the middle tunnel to do grapple skip in the new version i wasn't maintening right i just tap it at the good time and i was in so because the jump is still possible i think grapple skip is probably still possible if second screen give still give you the grapple anyway i wasn't expeting it so i fall but ...
EDIT: Yeah it's still possible it's just that accelerating from complete stop seem to take longer so just enter the tunnel at the right time xD personally im not consistent enough at it and at the game so i will not use it for now but ...
