Good morning lieutenant Ted!, you have been offered a special glasses, with them you can see the color of the souls of your loved citizens. As a karma police you sir have to invade the personal spaces of the suspicious,thief, smuggler,dealer, arrogant, nervous or affraid ones; just to tell what are their truly intentions and probably arrest them, you'll get a good raise if you catch the bad guys, but be careful, dont run out of personal space in yout intereactions with innocent people or your license will be immediate and permanently removed!

short brief

You have to navigate a crowded street/tube/etc without maxing out your proximity meter or anyone elses - otherwise you/they lose it! (thanks for the idea : https://ldjam.com/events/ludum-dare/42/$99837/my-ideas )
