I think some more monster sprites that aren't monster girls will add variety . I think only 8 such monster sprites exist at the moment (Plant , Ghost , Spirit , Skeleton , Scorpion , Bats , eye monster and Spider . Maybe add a normal clear slime that evolves into different monster girl slime depending on the environment ( like Eevee ) . It can also be a quest to evolve a caught slime . I'm actually interested in large monster sprites . I would like to see more new types since they are very few in the game ( Strange Demon , Minotaur , Golem , Demon ) .
