The latest version of the game (1.4.0) was used. There is no graffiti glitch, but pets boost stats properly.

This run is far from perfect of course, but I wanted to make sure sub 1h20 was possible before september's update. This update will bring new features apparently, so better wait for it before doing any other run!

Thanks to Potatohedron for his "save file" tip, and Lightbringer for the grind race in the sewers (upper route seems better, well at least with Otello)
