This plugin makes game testing much easier than ever before. With features such as Map and Item select, you can cut out all the tedious work you have to do within the editor and do it all in-game. You can open the menu through your main menu, or by using the plugin command "openDebugMenu" (and without the use of Text Overflow ;) ).
