Series: Time Value of Money
Water = Money · Freezer = Investment · Evaporation = Inflation
For Young Adults
Time Value of Money, the idea that money today is worth more than the same money later, because of inflation and missed growth, is easy to state but hard to actually feel, since cash doesn't visibly shrink or grow in front of you. Liquid Gold makes it physical by borrowing something everyone already understands: water evaporates when left out, and grows in volume when frozen. In the game, water is your only resource as you race to prep a backyard party before a deadline. Leave it out and it evaporates, value lost simply by sitting idle, just as idle cash loses purchasing power to inflation. Freeze it instead, and it returns later as more than you started with, mirroring how invested capital compounds over time. You'll spend the session deciding what to collect, freeze, or spend under real time pressure, with no coins, percentages, or finance terms on screen. Once the party's over, a Metaphor Mapping screen reveals exactly which financial concept each action represented.

Upgrade shop, plan before you play
The upgrade shop splits choices into income, storage, investment, and automation, each card a trade off with a real cost in liters. Players spend their liquid budget deliberately before starting the next day, feeling opportunity cost long before the vocabulary appears.

End of day summary
When the day ends, a full water balance sheet shows pool, cooler, and frozen reserves alongside evaporation and condensation earned. FinAI Coach reads the result and suggests what to try tomorrow, turning numbers into narrative feedback.

Freezer lab
The freezer room makes compound growth tangible: water moves from pool to cooler to frozen chambers, each with different risk and return. Players manage the full cycle in a stylized lab while timers and totals update live.

Oasis gameplay
The backyard oasis ties every decision to a place you can see, wheel, pool, cooler, and well under a desert sun. Meters track pool, cooler, and frozen water with zero coins or percentages on screen during play.
