This game is a gem, well done!
I love the whole feel of the spaceship. The visuals, the lighting, it's so good but I can't explain why. It just tickles me in the right way. Neat story, simple but engaging gameplay, lovely decorations and rooms, overall it's really good!
I don't really have much else to comment on, honestly. Yes, it's short, but it's fine as a self-contained story and it's presented really well imo. I don't mind the lack of enemies, in fact I find that it adds to the mystery. Making the ship and environment be the enemy is also an option and in this case it fits.
The only issue I noticed is that sometimes the framerate tanked while turning. That was only very early on in the game, iirc, and I didn't notice it again afterwards.
Good job!
