The fantastic puzzle game collaboration between Kitty Calis, Jan Willem Nijman, Jukio Kallio & Dominik Johann that has players experience minute-long days, Minit, is completely free on Epic Games Store.
This is definitely not an anomaly anymore as the Epic Games Store has been giving away various games for a while now, switching them out regularly, but it sure is welcomed. Next game to have its price cut down to zero is Surviving Mars that hits on October 10, so if you're looking to grab Minit for free, make sure to grab it while you still can.
