SteamAbout Idlemon
Idlemon is an idle desktop monster trainer. Played on the side of your screen, your monsters will gain experience, level up and grow stronger. Fight other monsters, get gold, buy items, and acquire new training buddies.
Train
On your island the monsters will train, attacking the practice dummy to gain experience overtime. When reached the threshold your monsters will level up, allowing you to use skill points to increase chosen statistics.

Fight
Travel to other islands to fight hostile monsters. This gives you more experience but also gold, used to purchase and upgrade items to buff your monsters. Watch out for the eggs, as they have a chance to drop and hatch a new monster you can train.

Don Let It Stop You From Work!
Idlemon let's you get invested in a new experience without the need to pay attention to it. Put it anywhere on your screen, resize or even turn on transparency mode if in need to get something done. No such thing as pausing.
