 ## 4. About the author(s)
 I'm Zughy (Marco), a professional Italian pixel artist who fights for FOSS and digital ethics. If this library spared you a lot of time and you want to support me somehow, please consider donating on [LiberaPay](https://liberapay.com/Zughy/). Also, this project wouldn't have been possible if it hadn't been for some friends who helped me testing through: `SonoMichele`, `_Zaizen_` and `Xx_Crazyminer_xX`
