So since I am planning to make more phases for RedJ Sans, as well as remake phase 1, I am making this from the ground up. I will make a project for every part, and then once I am done, start making my patterns, and making the fights. See ya! Oh, and the only thing you can do rn is move the heart.
Futures Lab for the tutorial. The only thing I changed gameplay wise is that you can hold x to go slow. @rias61 for model, and also has a template which the link is included in that project.
