BoneCrawler
Explore a dark gothic world and fight through fast combat in an NES-style action game.
About BoneCrawler
BoneCrawler looks like an NES game and fights like a character-action one. You explore a dark, gothic world in the manner of classic top-down adventures, then take on enemies in quick, combo-minded combat instead of slow, deliberate swordplay.
The creator, a solo developer, says the code was generated with AI while they directed the scope and tested the results. Claude, ChatGPT and Codex handled code generation and Gemini helped with planning, and the game was built as a reusable engine with an editor that the creator plans to open-source later.
It is openly a tribute to the games that shaped its author. Zelda-like exploration sits alongside the faster combat of Devil May Cry and Ninja Gaiden, all under a gloomy fantasy atmosphere shaped by The Lord of the Rings.
