Thanks for your feedback! It was suposed to have a tutorial screen on the beggining but i couldn't manage to make it appear :x, so, to pass trough the second enemy, you have to press "Z" and morph into BIRD-FORM so you will be able to fly through the scenary and when you finish, just press x to return to the normal form, thanks! (this game is made for my game development class in the college, so i will manage to finish it soon).
