Hello,I win using only the first ball, if that is not your purpose I suggest an obstacle so that you do not touch the blockwin. Also if possible place the first ball on a metal half pillar so that the ball falls without complications. If you can edit it before other players download your level.
2 tap win Spoiler: using autopilot to jump from the draggable slider . I'm pretty sure it's not intended.
Probably unintentional but so many ways to win at each winblock makes for a fun challenge. My hardest win was for R at the central winblock .
