Slide the color slider to fit you, then press the edit button to change the name. Press the pattern button to change the pattern and slide the pattern color slider to change the pattern's color. There's also a white soul outline and cross if you press the pattern button 3 or 4 times.
Note that this project is discontinued, and so I will not be making any changes to it. However, this project must live on! Check out Undertale Soul Creator 2.0 by ThisIsSammy, it's really awesome and adds things I wouldn't have ever added had I not discontinued this project. You may suggest things there. This is my most viewed project, I thank everyone who showed so much support on this. It nearly has 1,000 views! NOTE: No more "Saved Souls" list! Reason is there's no cloud lists. Probably because that would clutter up the cloud. Added Black Patterns (Request by @ECHO_WINTER) Thank you all for 972 views! Thanks to @AsrielDreemurr0505 for giving me the pattern idea.
