This is a world with four zones. Hunt the monsters that appear in this world and raise their levels to become stronger. Become stronger by catching the top monsters in each area.
Catch monsters, swing your sword, and become stronger.
It is best not to challenge enemies that are not of your level. Fight them and you will find out why.
You can check detailed keys by pressing esc, but the only actions the player can perform are moving, rolling, jumping, and attacking.
