GOG is having a “Pixel Worlds” sale, with deals on games (DRM-free as usual, of course) that use pixel graphics. It will continue for two more days and change.

My personal highlights include the following three metroidvania titles:
Chasm -75%
Phoenotopia Awakening -60%
Timespinner -50%
There are several pages of games on sale; others famous ones include Stardew Valley, the Contra Anniversary Collection, two of the Shantae games, and One Step From Eden (i’m gonna pick up that last one).
oh yeah i forgot about the Metal Slug games! haven’t played them yet though.
