CryptGrid door AnhTan_Dev

CryptGrid is a turn-based tactical roguelite contained entirely inside the Firefox popup. Explore compact procedural dungeon floors, fight enemies, avoid hazards, collect gold and potions, and reach the exit after clearing each room. Blade, Arcanist, and Shade classes use different abilities and cooldowns, while relic choices modify the rest of a run. Enemy movement advances only when you act, making positioning and ability timing important. Run state and earned echoes are stored locally in Firefox. The extension does not require an account or external service.
