I liked this! I started off by aimlessly wandering around, until I hit another planet or asteroid. At that moment, I understood the idea. You had to avoid slamming into things. So I restarted. The next time, I avoided other planets, until I realized the sun, and began orbiting (the gravitational pull of planets was brilliant, by the way). I noticed the bar in the top-left going up, and suddenly realized that you needed to keep warm by the sun, something I hadn't realized yet. In addition, "orbiting" was a good strategy for staying alive, and so I stayed in orbit, until I realized that it got easy. I thought it was going to get boring, until the sun exploded, and realized that you understood the same thing that I did. It was a really memorable moment, when I realized that my means of survival was gone. I had so many "a-ha!" moments throughout the game, and the game was designed very well. I don't know if this was intentional, but it worked. Finally, the music fit the game well. Great job with this game! I enjoyed it quite a bit!

Thank you for the thoughtful review! It sounds like you noticed a lot of the mechanics we tried to build into the game, mainly ways of making the player feel anxious and alone while they try to survive in the emptiness of space. And I agree, having your sun collapse is a striking moment :)

Makes for a really cool experience and it's fun to play.
