Re: Point 2, enemies healing very quickly. I checked the code, they SHOULD (excluding unforeseen consequences) heal 1 hitpoint every 32-60 frames (depending on their eating animation lengths, a shorter animation means quicker healing), WHICH IS once to twice per second (it's the worm that heals every 32 frames, and I could probably artificially slow that animation down to take 48 frames instead...?)
Is it ACTUALLY true that enemies take half damage once they have captured a player character? It really limits your DPS- if it's not true, that'd get you double the friend-saving DPS and make Mirea plenty effective at saving characters.
