“Exo One is a journey for the curious mind. Navigate your probe using gravity manipulation and explore amazing alien worlds until you find your way home. Beautiful visuals and freedom to explore; the constraints end up…”

“Wow! Bravo! This game is very original in the way it makes you think of how to use the gravity enhancer thing to get your probe to move where you want. I love the visuals, and the lack of objectives, maps, or even a HUD…”

“This isn't quite what I expected from the video demo. I thought this was a simple journey to different environments, and it actually is, but I didn't expect to do it as a travelling ball. Having said that, the game is…”

“Amazing little game. 10/10 Soundtrack and atmosphere. The controls are easy to pick up and provide good feedback. I found it best to play with a controller.”
“Fun and simple gameplay, genuinely beautiful visuals, there is a story but im too dumb to understand, amazing soundtrack. Pretty awesomesauce especially if you like space.”
“Great and relaxing game with a nice atmosphere, simple in its mechanics but effective in what it does, finished in less than 2 hours, recommend for 3€.”

“Really good looking game, You can finish in 2 hours. Can recommend. Only thing i wish is that after end game, there would be a free roam mode, with the music constantly playing, and the different planets change at…”
“Exo One kind of steals the plot of Interstellar and the mechanics of Tiny Wings, but if you can get past these things, the short length, and walking-sim type of game-play (Get from point A to B, no challenge involved,…”
“Short, soothing 2hr game, that mesmerises you with its attractive environments, smooth gliding and rolling around, as an Alien artifact. Didn't really understand the story too much, but traversing through the seas,…”

“Cool idea, nice visual effects - not bad, per se. I'm giving a negative review because I simply didn't enjoy it - It felt like a chore. Perhaps part of the problem is the gloom and doom vibes, everything feels sad for…”

“genuinely so underrated. I especially like playing it whilst listening to C418's Excursions album, they go together so well. not saying the original soundtrack isn't good I love that too”

Exo One is a meditation. I almost wish there was a mode to turn off the weird…”
— a player, Steam review · 3 hrs played“Its visually beutiful, has great music, and I found the story enjoyable. There is nothing inherently wrong with the gameplay, but it is not quite engaging enough for the entire duration of the journey, which is not particularly long. In essence this is a more involved walking…”
