The_Sink

This mod is a development tool that allows you to execute Lua code inside "Teardown/data/run.lua" while in-game without needing to restart. The most useful feature of this mod is the ability for it to display print() messages and errors, which makes debugging certain code easier, and the ability to easily hook and un-hook functions to the hud.lua's draw() function (which lets you do stuff like draw UI on the screen without modifying any 'core' files).
