Interesting concept, I liked the story :) Not sure if I finished the game but I couldn't get past a blue empty screen at the end.
Hm.. There should not be any blue screen. Where that happened?
At the end of the very hard level, once comets started falling, at some point I had a blue screen for a while, and by moving right side I might have fell in the void or something and I died :p
Oh. Thank you for the information. We will check it and hopefully solve the problem.
