I made a pretty straightforward template for editing the phone screen.
The solid color layers called "Template Outline" 1-4 are there to serve as selection tools to either create layer masks or to cut the images you're using properly.
The default symbols folder is there for you to add back smudges if you want them or to use the default symbols the game uses rather than your own!

The PSD file is for photoshop users and the XCF is for GIMP users. You do not need both!

Go nuts!

I am not going to teach you how to mod this game in the comments. Go to the discord not here!!!!
