An original game mimicking Mario Bros with Felix Sr. and Felix Jr. Made in Gamemaker Studio 2 Using MAME controls, customized settings, and created in a retro 640x480 resolution and graphic style.
This game uses standard MAME 2-player controls but can be customized with a settings.ini file
This game was made entirely in Gamemaker Studio 2, primarily with DnD (but also some straight code). Should complile in Gamemaker Studio 2's IDE fine for Windows. Haven't tested for HTML5, Mac, or Ubuntu.
I built an entire cabinet around this game, with new artwork. Read more about that build here: https://sergiostuff.com/2020/04/15/felix-son-arcade-game/
