Maybe when you get an Achievement make it not pop up on the screen covering the 8 helicopters shooting me in the back? Other than that very nicely done
Maybe instead of screen panning with the guy make an indication arrow with distance counter. This way you can retreat and see where you are running too.
Ok for the second Boss! Go to the top of the screen and when it starts to rumble on screen run straight down to the bottom. He will throw a spear and miss every time!! Simply grab it up move about mid screen and throw it at him right as he gets to you, grab up your weapon quickly and attack like crazy! He is really simple I promise!
