Kingdom: Classic is free to keep on the Humble Store right now

Released in 2015, Kingdom is a sidescrolling, pixel-styled management game about the trials and tribulations of royalty. You play as either a king or a queen, and it’s your job to make sure your kingdom doesn’t decline and perish. This is achieved in numerous ways—you can even toss cold hard cash at your subjects to win them over—but as James noted in his review, a zen early game quickly becomes very stressful.

The game is currently free on the Humble Store, where it would normally set you back $5 (AU$7). You’ve got just over six days to secure it, and once you’ve secured it, it’ll be yours to keep forever. Redeeming the offer provides a Steam code, and it works on Mac and Linux as well as Windows.
