Very cool game! I liked the idea of going around trading/battling in space! Also, the menu was mad nice, I didn't understand at first and pressed mouse to check, and hit the Start asteroid.
Managed to get to my planet on the third try, I guess the damage upgrade one planet can give really makes it easier to just go around blasting everyone.
The combat was alright, though due to aiming with the mouse to move I felt like I had to always become an easy target in order to engage other ships, so combat felt less dynamic, we'd just face each other shooting and hoping the other one dies first. Might have been by design, but I think a more action paced combat would suit the game!
I felt some of the sound effects could have been more "powerful", like the planet explosion and the other ships firing. The music when you engage into trading with a planet though was neat!
Regarding the visuals, the background and planets are very nice, though I found the font a bit confusing when it explained your backstory, some words seemed to close to others. Also, on some of the clearer planets, if the merchant text appeared above the planet it become nearly unreadable.
Really cool game and it feels like it has a lot of room for expansion!
