Ok, I am the one who made the game, so I will give a lot of hints!
White enemy bullets home in on you, but they dissapear eventually. Keep dodging them.
At 10000 points, a big enemy boss comes in very slowly and takes a lot of hits. The best shot for this gut is triple shot. He comes in every 15000 points after that.
ALWAYS GO FOR YELLOW POWER CORES! They increase your shot power. 8-Way Shot (6 Power Cores) = Killing Machine
Green Power Cores are Rapid Fire. You can hold the space bar and it will rapidly fire rounds of bullets.
Red Power Cores are health ups. There is no limit to health, so grab them even if you have 10 health.
Blue Power Cores are speed up. These increase your speed (duh). At first, (5 speed = default) you can't catch up to power cores belind you no matter what. After a few of these, you'll easily be able to catch up. Max speed is 10.25.
Purple Power Cores give you a random score bonus. Remember this if you are close to 75000 points. Every 75000 points, you get an extra life!
HINTS AND TIPS:
Avoid crashing into enemy ships. It kills them, but you lose life, too.
Keep Moving- Many bullets are fired toward you or home. If you move, there's a less chance that they will hit you.
If there's a big ship on the screen, kill it at all means. If it hits you, YOU DIE!
The round ships give you less points than the pointy ones, but take less hits to kill.
8-Way Shot + Rapid Fire + Max Speed = MAX KILLAGE!!!!!!!!!!
If you run out of health, you die and lose a life. When this happens, all your shot powers, rapid fire, speed, and health are reverted back to normal. Try to reach 8-way shot.
I hope this helps!
