what is Idlemon?

Idlemon is a desktop idle monster taming game where monsters fight, gain experience, and you collect eggs and cards to upgrade.

Idlemon is an idle monster taming game played on the side of your screen, where monsters battle others to earn experience used for upgrades. Rare eggs drop from defeated creatures and can be exchanged for card packs to unlock new cards. The game includes mini-games for extra experience and offers ambient sound options to suit your focus while studying or working.

It sits in the Idle / Numbers / RPG / Prototype corner of the genre. Like most idle games it runs on a simple loop — earn, reinvest, automate — but the depth is in how long that loop keeps unfolding. Expect to check in, make a few decisions, and watch the numbers climb whether you're at the keyboard or not.
