I have no idea what I'm supposed to do. I die once, twice, three times, without any clear reason how or why I'm supposed to do anything. I don't use my thrusters, but they run out anyway. I haven't seen a planet since I left the solar system, and until this game actually tells us what to do and walks us through the opening stages of doing it, it will not be a game in my eyes. That said, it appears to be functioning, so I suppose I can't give you NO stars.

same music as scale of the univers or univers scale

THAT WAS THE WRONG WAY.

I thought it was pretty fun, until I got back to Earth, then got hit with Spring Gravity. Now I'm stuck out by, I think Jupiter, with HUGE gravity fields pushing in. Try as I might, I cannot get out, probably because I never had a use for the Boost before, so I didn't bother improving it.
Beyond that, the only other issue I had was attempting to navigate to a good planet, and either drifting into another as I adjusted course, or having it drift into me.

It's an okay game. The music and atmosphere are nice, and the art style is clean-- but the actual flash window is way too zoomed in and there doesn't seem to be a whole lot of other gameplay aside from flying a ship around, which is fine, but there could be more here. Keep trying!
