Make an option where if you want to play around, you can enable it. Toppings, a score bar and a rank medal will show. Pressing ESC will give you the respective rank screen.
Do what they did in scoutdigo/19' plus; They rubber band to your mouse, which will make it harder to get away. Also, make a setting where toppings spawn to get good ranks (if you're not really trying to focus on something).
