Use up and down arrow keys to move. Press space key to shoot. Press m key to launch your special weapon. And don't touch the asteroids!!! Sorry there might be a few bugs when going into the shop or the rocket ship section but just keep pressing the back arrow when the bugs happen.
FYI with the golden rocket you can hold down on the mouse to shoot. If the project is to laggy go to turbowarp mode: https://turbowarp.org/636070467. Don't forget to go to my profile to check out some of my other games! https://scratch.mit.edu/users/Rocket99zero/
