this is going to be really hard to balance, i think i has now gone in the other direction, i also got all the way to leviathan, and was basically invincible. I could heal any damage because pen cannons were so good. I basically had to try to die that was almost a struggle XD. When i was coasting, i accidentally rammed and killed some ships and then picked up a heal cargo...
(the time isn't as long as it seems i had to take a break)
