Good but insanely hard
Its a good game but the last boss on c-5 will have you pulling your hair out. I dont know how someone is supposed to beat all 20 levels in succession without dying and I dont want to be the one to put myself through such stress.
I did notice that some of the secret medals did not unlock for me but I wont say which ones as to not give it away but maybe you should include an option to resend although the game itself is saying I never earned them either which is ridiculous as I have over 100k points thanks to the very last screen. I didnt take off points for the medals not working however.
