What a major project!

I really liked the atmosphere and I agree with the previous comments that what's missing from this project is basically everything you've put on your to-do list.

That huge creature had me bloody worried! It took me a while to realize that it wouldn't hurt me. At one point I even said to myself, “It's not hurting me at the moment! Maybe if I extract 250 biolum, she won't be too happy!” 

In short, a great game! I can see why it took you so long :D Well done!

Ho man, I went in the game blind and I thought I was just going to gather minerals. I was REALLY concerned when I went back to refill my oxygen and I saw red lights moving on the map. I was thinking "Wtf is this??? 👀". When I came close to it and I saw the HUGE fish, I was spooked!... but then I realized that the fish couldn't hit me which was a bit anti-climatic. Don't get me wrong, I've seen your to-do list and it's great that you were able to do this much! I also like the mechanism to gather minerals! It made me think about the system to attack in Undertale!

Overall, great work! Keep up the work!

Very good game. I think sound effects would add a lot. I only managed to get 238 until I died. My strat was to go directly to the golden and violet ones. Your todo list is basically everything else I would add to the game to make it nicer. I really liked the creature that was always around and although it didn't do anything it was still a nit scary. Good job!

The game appears frozen to me; it might need a quick check and bug fix.
