I'm Arthur (also known as Tui), a game developer from Brazil with a bachelor's degree in computer science.
I'm into free and open-source software, which most (maybe all?) of the games here are, and that's also why I use the Godot game engine.
I'm also a part of USPGameDev, a group focused on making / researching games at University of São Paulo. Most of the game jams I've participated in have been with them.
