Epic Games recently launched their own digital storefront to compete with the likes of Steam, and they're offering deals for developers and players alike. Developers get to keep 88% of profits generated on the Epic Games Store (a much bigger piece of the pie than Steam allows), and players get regularly-scheduled free games. Last month Oxenfree was free to download, and now it's been swapped out for another indie.
As of yesterday, you can pick up Jonathan Blow's The Witness free of charge. Given that this game is normally $39.99, that's some pretty solid savings! The Witness is a beautiful puzzle game that gives you free rein to explore an island and unravel its mysteries. It will be available for free until April 17th. The next day it will go back to its usual price tag and Transistor will take its spot as the free game on the Epic Games Store.
