Use your left and right arrow keys to move. Press space to fire. There is a main menu button on the bottom left side of the screen that you can use to select you difficulty. If anything goes wrong, just run the thing again. :) Sound recommended. Pro tip: I do NOT recommend quickly switching from Easy mode to Hard mode instantly if it is your first time (unless you think you're good enough and you want a bad time). (Kamikaze works by the way, just mind the fact that crashing into planes means you are crashing too).
This was an indie game (only one person created it).
