Chou Mashin Eiyuu Den Wataru - Mazekko Monster 2 — About this game
Raise Monpets and work toward collecting five dragon types, paying attention to their care rather than treating every choice as a battle order. Play outside, offer food, talk to the creature and let it sleep as its development marks fill. When the evolution conditions are ready, sleep brings the next change. This sequel also lets you make food yourself, linking supplies to the care routine. Check the creature’s condition before repeating an activity and adjust the next step as it grows.
