This was great!! The color palette, the fog, the black sun... fantastic atmosphere. You really nailed the low poly horror feel. Solid sound design. Loved the story and dialogue. I got 2/3 endings so far, definitely gonna have to come back later and try and get the first one.
Some small suggestions: I would add in an option to skip the cutscene at the start for people trying to play again. Also, I was able to just walk around in the desert past where all the cacti were, which I'm not sure was intentional. Maybe there could be an ending for "you got lost walking around in the desert"? Unless of course there is one and I just didn't find it, haha.
