High score of 2545... That doesn't seem like it's that high based off all the zeros in your score meter, so if it is a good score, maybe a few less zeros would help let me know that? Unless my score really is as bad as I think it is lol
It took me a while to figure out which asteroids actually had something interesting in them, and once I realized I was getting points just by not getting hit, that was the approach I took. Maybe I'm just a risk-adverse person, but why take the risk of letting Eva suffocate if I can get points for just pulling her around? I'm sure you get more points when destroying asteroids, but I have no way of see how close I am to destroying one (maybe add a deterioration sprite like Minecraft does?) and the ones with stuff in them come by so infrequently, that it doesn't feel worth it to me to chase them down.
Your assets are very clean and clear, though, and I love Eva's little quips when you detach/reattach her!
