Triangle Keep

What it is

Triangle Keep is a castle defense strategy game by itch.io creator jonson-lee, playable in the browser. The map is a triangle grid: you drag walls to change where enemies gather, steering knights and orc soldiers into battle to keep the king's castle safe. The creator says the game was built with OpenAI Codex under human direction, with the king and wall art made using OpenAI image generation; it also uses Pixel Frog assets and a soundtrack made with Strudel and Superdough.

Who it's for: Players who like planning a defense on a small map, including on a phone held upright.
