woahhhh! if you get really far and are going fast enough then it messes up your vision. Right now there's a line in my vision. It's going to the left. The rest of my vision is going to the right. WEOHHH! FUN 5/5!
:| I beat this entire game on armorgames a week ago, and reset my cookies so I couldn't screenshot the all golds GUH now to do it all again.
Anyways, its possible to get all gold without black hole, but very difficult.
Final boss took a few minutes to figure out, but when I realized my "annihilator" gun had a longer range than the bosses missile systems, I just sat out of range and fired until I destroyed him.
