Whose bright idea was it to have a final boss so big it doesn't even fit on the screen? It's hard to fight what you can't see. Also, I haven't figured out if my bullets/rockets persist off-screen and do damage to the boss or not. Zooming out further would've been an easy fix.
For level 10 on Hard you'll need at least 5-6 nukes and a bunch of rockets. I had 90-100 rockets, 7 nukes, and all upgrades of course, and I barely got through it with 10% health. I used 5 nukes so I ended up with 2 unused nukes at the end, and I didn't run out of rockets. I forgot about using EMPs, but I bet nukes are more cost-efficient.
High score 592 seconds from a year ago. 584. Suddenly, 892 seconds! WTF? Luck plays a huge factor in this game. Not just the asteroids, but the powerups as well. I got 2 shield powerups within the minute before I died!
