... By destroying its 48 HP, one bullet at a time.
I attempted to optimize Planet 1 for a bit. Every subpixel I could save. Wasn't enough for another frame (still get there by 892).
I did optimize the initial pick up of that fuel cell so that I would rush to that enemy faster. I also shot some enemies who were off screen.
Navigating the next part in a speedy manner looks tricky... Corner ricochets have strange properties, but apparently not good enough here...
I still am lost as to how to bypass the big enemy without destroying it. My attempts at maxing out the enemy counter didn't work out.
Warps route.
