WARNING: Friday Night Funkin Mario's Madness contains blood, unsettling themes, loud noises, and scary content. Play at your own risk. This free online FNF mod is hosted at fnf.gosprunki.net and brings a dark twist to the Mario universe.
Special thanks to @sussybakunsta for providing the background images – the creator couldn't locate them in the original game files. The mod includes fully completed sprites for mario.exe and GB songs. The creator is aware that some sprites are still missing and is actively working on them (exhaustion has caused delays). Updates: Luigi icons, Luigi sprites, beta Luigi sprites, icons, and all backgrounds are now finished. The mod is now fully completed. Wario apparition has been added and is pending coding. Original mod by @cabalex – current version v25v4b.
Default controls are DFJK or arrow keys. You can reconfigure them anytime in the options menu. The game is fully playable online – no download required.
