This is amazing! It totally gives off the wasteland vibe.
Art: 10/10
The browns and greys give off the feeling of a wasteland, and the art in general is just top notch!
Sound: 9.5/10
The lack of music helps sell the alone feeling.
Gameplay: 8/10
The gameplay is good, although the controls are slightly clunky, it's not a big deal.
Overall, it's a good game, and I think it totally is a metroidvania and a fallout game.
