An optimization companion for the idle-RPG TBH: Task Bar Hero. It reads your save locally in your browser, decrypts it, and tells you the optimal next move: where to farm, when to come back, when you'll level, and which runes and gear to get.

FARM

Ranks every cleared stage by gold/hour and exp/hour from your real clear speed.

IDLE

The best time to come back, and what to leave running while you're away.
