The overall mood and flow of the game is pretty great! You're alone in space, a very chill and nice soundtrack is playing and you blast through asteroid fields. I like that!
Using your thrusters to navigate works pretty well, although having a forward and a backward thruster led to situations where I used the wrong one and this can be pretty deadly in an asteroid field :D
It's also pretty great that you use the temperature as an indicator of how far away the star is. This totally fits the space and heat them and is a nice detail.
Overall a pretty good experience. Well done!
