Loneventure is single player puzzle map, which solely focuses on puzzles and platforming. It takes about 3-4 hours to complete.To play the map, download the file from the link and move it to your maps folder, which should be Documents\My Games\Terraria\Worlds.
Important: Most of the items and mechanics the map uses doesn't work properly on version 1.4, so you will have to use an earlier version. The easiest way to do that is by downloading tModLoader, then going into your Steam library -> right click tModLoader ->Properties -> Betas -> 1.3 Legacy. After that, uninstall and reinstall tModLoader. (Guide if needed.) You don't have to install any mods, tMod will simply act like it was a vanilla 1.3.5 Terraria. After downloading the map from the link, move it to tMod's worlds folder, which is Documents\My Games\Terraria\ModLoader\Worlds.
Rules:
-Create a softcore character, then trash your copper starting items after you enter the map.
-Do not use any items dropped by enemies, or the environment.
