Dark Deal: Convenience Store Management Simulator

A Deal in the Dark - Convenience Store Management Simulator
50,000 gold in debt, one month to survive. The darkness is after you.

🏪 Introduction
You are the new 'manager' of a suspicious convenience store. You've inherited this store along with a debt of '50,000 gold' from the previous manager. It's the result of being deceived by a high-salary advertisement. If you fail to clear the debt within a month, you'll face the terrible fate of being 'subservient to the darkness'!
This living convenience store is your only means of communication and key to survival. Instead of speaking directly, the convenience store will convey information to you through bizarre phenomena occurring within the store, sounds coming from the speakers, CCTV footage, and more. The convenience store will react in various ways depending on your choices and actions, and this will be a crucial clue that determines survival or destruction.

📜 Key Features
Dual Life of Day and Night: During the day, you greet ordinary human customers, gather clues, and earn small amounts of income. As night deepens, the convenience store becomes connected to the 'darkness,' and unidentified 'grotesque' customers make strange requests.
Debt Clearance for Survival: You must repay the 50,000 gold debt within a limited time of one month. If you succeed, you gain freedom, but if you fail, you become part of the darkness.
Communication Device Upgrade: You can upgrade the old switchboard under the counter to improve communication with nighttime customers and increase your chances of survival.

☀️ Day Business:
1-3 human customers visit randomly and purchase general goods.

Ends with the message "Day business is over. Today's daytime revenue is 50 gold."

🌙 Night Business:
Starts with the message "Night has deepened. The convenience store is connected to the 'darkness'."
A black curtain is drawn over the counter window, preventing you from directly seeing the appearance of nighttime customers.
'Grotesque' customers convey strange requests through the convenience store.
If the transaction is successful: Reward of at least 100 gold or more.
If the transaction fails: Loss occurs and debt is added. Failure conditions include not providing the desired item or making the customer uncomfortable.

🔧 Communication Device Improvement:
You can upgrade the 'old switchboard' under the counter.
If the manager expresses the intention to upgrade, the cost (500 gold per level) is deducted from the funds and the effect is applied.

Bizarre transactions with unidentified beings, the eerie atmosphere of the store, and the unpredictable story created by your choices unfold.
