Before you start
This game runs fully offline and stores scores on this site only. Continuing means you agree to play as a guest or a logged-in user; logged-in scores are written to your save and the rankings.

Refresh
Restarting returns to this floor checkpoint; starting over clears the current run.
Saves
Settings
Auto battle is always available. Speed-ups: 2× at floor 20, 4× at 100, 6× at 200, 8× at 400 (based on best floor).
Higher wins; score = weight ÷ (1 + current level).
Idle
Challenge results are tracked separately and excluded from adventure rankings.
Export all saves, challenge progress and settings as JSON; importing overwrites matching data.
Drop a same-named PNG into assets/sprites/ to replace that slot entirely. Missing files fall back to procedural art; reload the page after changing files.
plugins/endless_mobs/assets/sprites
Edit the exported PNGs and put them back into assets/sprites/; missing files still fall back to procedural art.
Challenge Mode
Doom Barrow
Fight an empowered boss floor by floor; each kill advances one floor, starting at best +1.
