Use Arrow keys to navigate and space to shoot and 1 and 2 and 3 to switch guns I recommend machine gun or ray gun. ( ray gun is complex to use but, if you learn how it is a very good blaster.)
a huge thanks to Tomatoboy800 for the original game, I liked it so much that I couldn't help but remix it, thank you tomatoboy800 for a very thrilling game.
