To play, click the green flag. You may need to click it twice. Then, click the spaceship you want to use during the game. It is also the difficulty. The red rocketship is hard, while the green one is easy. You are invincible when you are on easy mode. When you have started, use the arrow keys to move around. Don't get hit by the bats. You win if you get 1,000 boss hits. THE RAINBOW BALL IS NOT YOUR ENEMY!! It actually helps you. You can control the rainbow ball with your mouse. You get a force field every few seconds. Click space to change the color of the force field. To win, you have to get 1,000 boss hits. You have to use your laser only. If you die, you cannot restart it. You have to click the green flag again. This project was actually not very hard to make! There are not much variables, and no difficult formulas and whatnot. There are not a lot of blocks. See inside my project for yourself.
