Nice one! I see potential in this game. First, let me start with what I liked: love the music. Love all the Achievements: that's a lot! It feels cozy and chill playing; as it should. I don't like that, at some point in the game, everyone moves toward you in a circle and kills you.
That being said, I have a big problem with ALT+TAB or any notification during playing—makes going back to the game almost impossible and I have to quit. The stars that are on the same layer as the ship should be on a different layer. Why is the screen square? Try to make the game more modern. The upgrades that you get when you kill a big ship have no description (says Description here, LOL). I think you should keep working on this game, it could be a lot of fun. Absolutely loved the light saber on the first ship. WOW!
