Steam user katyarun has posted this brilliant full walkthrough video for Tricone Lab: https://www.youtube.com/watch?v=4UV_AUr5OY4 It's even broken down by map, with a little on-screen indicator for level. Perfect for helping you beyond that particularly difficult level, or for just having a look at the game content. Each level is solved quickly, the full video is about 1 hour. Thanks katyarun!
