Doom in Space

CONTROLS: arrow keys to move except for the down arrow key and click to shoot.

Hello, 

I've made a few games before but I never came close to finishing them, so this is my first EVER finished game.

This is just a small DOOM fan-made game, with two powerups you can obtain, invulnerability and being able to shoot 3 rockets. I did work a ton on this but not THAT much lol, I did work on this for three days on GameMaker, my first ever game making on there so I am learning, and I did get a lot of help. From Youtube lol.

Hope you enjoy this game I made! I have many more to make and will continue to improve as much as possible, it's my dream. Also comment down your highest score! Let's see who can get the highest.
