Hello, first of all I want to say this game is so much fun and I love it. So far most of the problems I have seen are just misspellings or "dev clearly has not implemented this yet" situations, but I did want to stop here and say that as a mobile player, I cannot see any of the art at all.
As you can see I'm playing in Chrome browser . I can see all the art files sitting in the assets folder but they won't work in the game itself. (In addition it looks like there's an extra list ending tag on Nico's profile.)
