yep issue that fresh character need to move between lot of level 5 and 7 even 9, give some cooldown how often they can fight between themselves or essence/size gains from those fights to mitigate those absurd leveling
Part of the issue is also how far they can move in a single "turn", just zoom in out of the fog, I don't know why enemies can move further, but they can also move diagonally...while the player can't, which is also a bit over powered
I think part of the issue is the size of biomes, they might be to small causing many to overlap and "feeding" one or two enemies
