Great game! I love space travel sci-fi stuff, so the exploration was really fun and the lore books were a cool addition. For the criticism I can give:
- Sometimes it felt the eyes were coming from below me in the planets, though I didn't get killed for it at any point;
- I did like going through the planets, but I skipped the last one because it didn't feel worth it to face more danger if I already had the mothership on sight (and because my life support was almost dead already :P but that's a skill issue);
- One minor accessibility nitpick I have is that the sensitivity slider didn't seem like it ranged enough, I had it at max and even then it was a bit below my standard (which stands pretty low on the sliders of most games I play).
Overall though, the game looks and sounds good and I very much had fun with it. Awesome job and awesome entry!
