100% route used by GreenUprooter during January 2018 WR. Includes extra information about which Star Coins to get in each level, when to go to the Secret Exit (Secret), when to enter Star Houses (SH), when to use Super Stars (Star), and when to enter Cannons (Cannon). Info before the level name on each split indicates that those actions need to be performed (in order) before you enter that level. (direct download)
