New to this game but having fun. Most of my "scores" for the built in levels are much higher than "The Light List". But my Level 17 - Catapult, had $210 left.
I don't know how yet to pass the approach to the forum.
I Put a sheet metal plate on the right side hooked to the lower right node, and rope under tension from the upper left node, rope from upper right node under tension and short timer both hooked to top of metal sheet. Start, AR flies up, right rope snaps, AR flies by nodes, metal sheets are pulled below AR and catch AR as it falls back.
Something like that!
Cheers,
Dilly
