How are the game logic and the economy designed?
Most of the work in a game like this is rules, not graphics. We write down how points are earned, how energy refills, what daily streaks pay and which upgrades exist. You approve that document before we write code.
Points are calculated on the server. The client reports what the player did and the server decides what it is worth. That lets you change a rate later without shipping a new client.
An admin panel lets you change rates, pause a season and review flagged accounts. How generous the economy should be is your decision. We cannot predict how players will respond.
