nice try, but an explanation of what the power ups are/what they do would be nice. also the ship doesnt always stay one ship. it kinda splits sometimes and looks really funky. i think the code needs to be tweaked. also (i like that word: also) the bad guys shoot waaaaaaay too often. they need to shoot less or the main ship needs to be smaller. and faster for that matter. also, its pretty annoying that enemies can fly across the bottom of the screen.
about the double jump creatures(and others as well): if you werent told you needed to learn to double jump then you wont learn. also if you were told and then died before you saved, then it wont work. youll need to go back to where you told you needed to learn it.
