press Z to start, press X to stop, flag to reset, right and left arrow keys to steer, up arrow key to dash and space bar to shoot down missiles/boss ps: should I update the sprites (type in the comments)
My edits: added an enemy health so that the gun actually can damage/kill the enemy and a limit to how many rounds the player has. Maybe instead of having the aircraft bounce off the edge, if they hit the top/bottom, multiply their y value by -1 and if they hit either side, multiply their x value by -1. This will make the game more like one with a scrolling function and is a little more realistic. Any scripts with a comment were edited by me.
