The Catacombs of Eye

A browser-based dungeon crawler where you escape by writing SQL; each room is a puzzle, and your only weapon is a SELECT statement.

Trapped in a dimly lit dungeon, you progress room by room by querying a SQLite world. Explore tables freely with Run query, then Attempt when you think your result opens the door. Wrong answers cost HP and unlock hints; run out of health and you respawn on the same floor. Eight rooms across four floors teach SQL step by step; from WHERE and JOIN to subqueries and window functions; until you defeat The Slammer and escape.
