My Tips So Far

Gold: Needed for opening and upgrading (buildings) shops. Energy: Needed for generator item output. Shop Cooldown: You can get gold and energy when it's fully charged. Initially, it's usually 5-6 hours. If you max out the cooldown level, it takes 4 hours to fully charge. Generator Cooldown for Each Item: I've heard it usually takes about 10 minutes to fully charge. Stars: You can get them by maxing out certain items (dog food, cat food). They offer many benefits, such as increasing the amount of gold and energy you can receive upon cooldown completion, or reducing the cooldown time. Personally, I prioritize maxing out the energy quantity first, then reducing the energy cooldown (time reduction), followed by maxing out the gold quantity, and finally reducing the gold cooldown. This way, you can mine a bit more energy with the same amount, which increases the number of item syntheses during the next cooldown period, allowing you to complete quests faster. So, whenever I can check, I log in every 10-15 minutes.
