No Mario's Sky

About

No Mario's Sky is a side-scrolling adventure game that mixes exploration and platforming. You navigate procedurally generated worlds while collecting power-ups and fighting enemies. The game's open-ended structure lets you tackle challenges in any order, with a focus on discovery and customization. Developed by ASMB Games, it launched in 2016 for PC and Mac, offering single-player only. The game started as a fan-made project inspired by classic Mario titles and No Man's Sky's open-world design. Initially created for a game jam, it expanded into a full release before Nintendo requested its removal. Despite its short lifespan, it built a small but dedicated fanbase. The blend of retro mechanics and modern procedural generation made it stand out, though legal issues kept it from lasting long.
