◆RPG Developer Bakin Mokemo Factory MONSTER PIXEL PACK Vol.5

The fifth volume of the monster battler asset series by pixel artist Mokemo is here! This collection features 20 uniquely designed monsters, each with its own backstory—from a space traveler riding a haniwa-style camel, to a centipede warrior consumed by the madness of the battlefield, to a scorching predator that hunts with searing claws.
