Thanks a lot, I'm really glad you enjoyed the game!
I worked on the graphics for the characters and the drones.
The 80s leather bar enjoyer in high heels is probably the only realistic character, with a pepper spray added in his hand :)
The artist name Copi – Raúl Damonte Botana (1939–1987) – was an Argentine-French writer, cartoonist, playwright, and performer, active in the LGBT and avant-garde scene in France during the 1970s–80s.
The process was as follows: the characters were created in Photoshop using a collage technique with various photo fragments, then I altered their proportions using the Liquify tool, converted them into pixel art, and finally shaped them using the lasso tool :)
