This is the bizarre open-world indie game Sludge Life from Devolver Digital, Terri Vellmann, and DOSEONE. This is definitely an out-of-the-box concept, and there is very little introduction. Yet this is something truly special. Check out Jason Capp's review for more!
Half-Glass Gaming: "Sometimes you need a moment of respite after conquering a tough game. Here are five chill games you should play if you’re looking for something to sit back and relax with after getting through the anguish of beating a brutal Soulslike."
COG writes: Sludge Life lets you graffiti the world, and there's nothing more enjoyable than exploring a cool place at your own pace.
VGChartz's Evan Norris: "Sludge Life is paradoxical. As a video game it's short, shallow, and often rudderless. As an artistic experiment, however, it's powerful, expressive, and bold. Additional directives, more varied gameplay, and a bigger world would enhance the overall experience, but might dilute the thoughtful weirdness of the game. In any event, keep this one on your radar. Love it or hate it, you'll never forget it."
