An atmospheric action puzzle RPG in Three.js

I gave Sonnet 5.5 full artistic control for this game and told it to create an atmospheric action/puzzle RPG across 5 biomes, 5 guardian boss fights and it delivered, with some handholding from me. Understory is entirely drawn with code and made in a couple days. I am still constantly blown away at how much "taste" the new Sonnet and Opus 5.5 has. The ending is really poignant. Highly recommend spending the 20-30mins to get to the ending if you have the time. The game is built on ThreeJS with procedural 2D art made by code. You can play Understory here (Desktop Browsers for best experience):
