Scholar's Blight

You play as a cloaked scavenger looting a giant, ever shifting, ancient library while being hunted by an entity known by legend as the Scholar's Blight. Loot bookshelves to find poems which you can trade with scholars for lantern oil, keys to unlock new sections, and upgrades. The deeper you go, the more poems you'll find, but the farther you'll stray into its territory...
Collect enough poems to afford the Master Key and escape the twisted maze of hoarded knowledge.

This is a single file HTML game I made over the course of around a week using Gemini pro.
