Meeting Cthulhuian eldritch-horrors is my favorite pass time! I love the story and its potential to go many places; however, I am not a super huge fan of the gameplay. This may be a limitation of your engine, but I'd love to be able to see more of the screen so that I'm not blindly falling into pits and so I can plan my jumps better. I'd also suggest finding something (other than your beautiful graphics) to make the gameplay unique--collect all the coins platformers tend to lose interest quickly. Maybe you could play into the fact that you're in space and that gravity has very little influence. Maybe each of the monsters you meet have some effect on how you interact with the environment. Combining your story and gameplay in a meaningful way is a sure route to an interesting and memorable experience. Good luck, I'd love to see where in the universe you take this!
