Exploration and slime optimization.
The exploration was more just looking around, and since the game is finished I can explore to my heart’s content.
As for slime optimization, the farm has only so many plots of land. So mixing your slimes into mixed slimes lets you feed the slimes easier to feed and maintain.
The goal being a farm that doesn’t create monsters from free roaming plorts while making the most money.
I’m in it for the exploration and without guides its a good time sink
PixelJunk Monsters Ultimate, while I love the games music, it’s not necessary since it’s a tower defence game.
