I really liked the menu interaction for building and level selection. Felt very clean and was quite nice being able to look around the ship and also the planet, felt more interactive and enjoyable than a menu. On top of that, the rest of the game looks pretty good in general, especially the planet in the background and some of the HUD. My only gripe is the lighting in some parts of the game is a bit dark.
Also I kept running into issues with scenes or effects and what-not being loaded in for the first time, so there would be a huge lag spike or delay in the game. At one point my game just froze indefinitely because I crashed into another ship I suppose.
Besides those hurdles with the lag, the rest of the game looks and feels great. What little of the combat I got to play felt smooth and intuitive. I'm not sure how difficulty scales in the rest of the game since I wasn't able to make it very far because of the crashes, but I hope some challenge and differing enemy attack patterns do emerge because I was often able to shoot at far off enemies and kill them before they were on my screen.
Overall, like I said, the game looks and feels great. The animation as well is a nice touch. I can see you put a lot of elbow grease into this one in order to make it nice and polished. Keep up the good work!
