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.
