What players say

81% of 13,381 reviews are positive · 82% of 114 in the last 30 days

Players praise the pixel art, layered progression, minigames, and suitability for background play. The most common complaint is that meaningful progress requires too much active play for an idler; players also criticize progression walls, random buffs and equipment drops, and repetitive late-game grinding.
