These stages are straightforward. Simply activate your Cookies' skills as they become available. GingerBrave's skill provides a small stun, while Chili Pepper Cookie deals area damage. Custard Cookie III offers minor healing. Focus on getting 3-stars on each stage to unlock the subsequent stages and earn bonus rewards. You'll primarily earn Star Jellies and Gold here, which are essential for early progression.
Ensure you're also building your Kingdom simultaneously, as many early quests will require you to construct specific buildings or produce certain goods. Keeping your Kingdom productive will provide a steady stream of resources needed to level up your Cookies and expand your territory, making future stages easier.
