In the project.
All code is free to use with credit. But just a warning, if you use pen for another something else in your project, it will not work because at the beginning of code, it erases everything. This is able to be backpacked, but make sure you backpack the "define" script. If you are having trouble, please tell me in the comments of this project and I can help you. Also, 1 view in less than an hour, wow!
