Idle Monster Slayers - Clicker

In Idle Monster Slayers, you need to build up your units to collect gold that you can use to buy more units. This idle / incremental game has 8 unit types, upgrades for each, and achievements at certain intervals. Later in the game you'll start collecting soul orbs that give you a permanent gold boost when you reset. Gold is also generated offline so you don't need to keep the game open while you wait.
