This game gives me the same kind of lonely vibes as the Metroid series, due in part to the graphics you used as well as the story. I had a bit of trouble figuring out that the statues with their arms up were switches to open the doors. Maybe stereo sound or some visual indicator leading towards the door might have cleared it up. Or you could have made both the doors and the statues the same color. I eventually did figure them out, so it's no biggie. I did enjoy this game a fair bit, though!
