Create a new version of paste:

Note: This is not the official code. This is a shortened version of the code that uses 5932 of the 8192 tokens of code made by AFBU. I speedrun this game so I am quite knowledgable about it and from what i can tell there is no difference other than the code is shorter. This is handy if you need extra room in the editor for modding the game. Hope you enjoy. C:
