I hand drew 5-10 different nose, hair, eye, mouth, and head parts, which then get randomized for every person every time a new level starts. To not accidentally make duplicates for the criminals there are actually some specific parts that ONLY a criminal can spawn with, but after some playtesting from a friend it seems like it was hard to pick up, so the game still is difficult for the average player! Thank you for the compliments and glad you enjoyed the game :D
