Game elements Touch any element to modify its color using the color property. More information Once you're done with the theme, if you really think it should be included, feel free to make a pull request. I will check it out, and if I like it enough, it will be included in the game :)

Theme properties Change the theme name, price, shape and elements' color. Theme name: Theme name: Cell texture: Default Circle Bubble Piece color: Auto-trigger color selection Generated JSON Copy JSON

Once you're done, copy the generated JSON, and with your file explorer go to ../android/assets/themes. There, create a new *.theme file and paste the copied JSON in it. Add the name of the new file (without the extension) to the theme.list, and all done!
You can also do this manually without using this interactive site. Just copy any existing type and modify it at your will.
