Exo One is an experimental interplanetary adventure full of guilt and regret, and not enough awe and wonder

Continuing to go through my back-log of shorter games that I've bought in bulk on sales, I spent a couple nights going through an indie game called Exo One. Exo One is a sci-fi ... um ... adventure game? Puzzle game? Platformer? Infinite runner? I'm really not sure how to classify this game ludically. Exo One feels like somebody thought "let's adapt the last 10 minutes of 2001: A Space Odyssey into a game" So it's part 2001, with a little bit of Contact thrown in for good measure, and plays similarly to Journey (but without any of the multiplayer aspects that made Journey such a beloved insta-classic). Basically, it's a game about going somewhere, but without really knowing where that "somewhere" is supposed to be. As such, it's the journey that matters; not the destination.

The basic plot, as I understood it (because it's a bit trippy and difficult to follow), is that an alien civilization transmitted data to Earth containing plans on how to build an exotic interstellar space craft (hence, the Contact reference). When a crew of astronauts travel to Jupiter to test the spacecraft, there is some kind of accident or unexplained phenomena that causes one of the astronauts to become lost in space. We play as that astronaut trying to return home -- well, actually, it's a little bit more complicated than that, but what's actually happening falls into spoiler territory, so I'll just leave it at that for now.

The spacecraft itself is a metallic, shapeshifting ball that can transform into a discus-shaped glider. It is equipped with a "gravity drive" that allows it to temporarily multiply the the force of gravity that is applied to it. As such, the core gameplay loop consists of rolling this ball across alien landscapes, using the gravity drive to pick up speed whenever you are falling or rolling downhill, and then jumping and transforming into the discus glider in order to reach higher elevation or travel long distances.

What if the climax of 2001: A Space Odyssey were a game?

Yeah, it's a weird one...
