Hi there! Good job for your first game project!

I would try to implement more mouse controls on the UI screen. I constantly kept try to click on things when I should have been using the keyboard.

I also felt that some of the key-combinations on the UI were strange. I didn't know if I was supposed to press multiple keys at the same time or if it's an either/or option.

I noticed that when docking you can still fire the laser and run the engine (even though the ship doesn't move).

Finally, I would suggest having a single UI screen at the beginning telling the player what they need to do. I understand the core gameplay is mining asteroids, but I didn't know why. Something like, "Mine asteroids to upgrade your ship" or "Mine asteroids to get money to ultimately save your company from financial ruin" or something silly like that.

I thought the art style was nice and consistent across game assets and UI assets - good job!
