Instructions in game. Press R to reset. Now it supports "\", "_", "|", and "/"? "_" is probably in the style of where it may be in the style that fits the text style. Now it uses a list instead of it being a CHAIN OF CODE for the line text. The list gets messed with at the start, so don't render unless there's 24 lines of text in the text list. Part of the project is probably optimized, more specifically the Line block.
Thanks to ianrocks for the original project Rotating 3D Text Engine.
