A glimpse of how Jelliquid cities look! Basically a mix of Hydropunk and Y2K retrofuturism. This one is a city out of water.
Jelliquid architecture is varied and colorful- since money isn't a major part of their culture, building things is an easy endeavor- too much so in fact, which leads to Jelliquid cities being 'too big' and ruining natural landscapes.
At least, Jelliquids don't have cars- instead, they use the water tubes as shown in the picture. They're very wide, which allows several individuals- even big ones- to cross at once without getting stuck. The water they use in the 'transportation tubes' is clean- akin to pool water in terms of chemestry (so contains chlorine).
Many of the Jelliquid cities buildings are full of water, to accomodate their semi aquatic livestyles, and need for their environments to be humid. These buildings can serve any purpose chose by their owner, from offices to entertainment (ex: theathers, or in the case of the tall building with coral on the right- a big public pool that simulates the sea).
The habitations are generally the bubble-shaped towers. Each bubble is a singular appartment. Top floor individuals generally have access to a roof window- they're inherently the wealthiest of the building, as necessary things in Jelliquids society don't cost money. Instead, it's more of a luck thing- if you've got your eye on an appartment, you've just got to hope the owner decides to leave.
While Jelliquids don't use money for necessary things (food, housing, water, electricty, transportation...), they can choose to have a job, and get money to buy items and such that aren't essential- such as decorations and trinkets, new furniture, some holiday trips (only to far off places- close by destinations are generally free and can be accessed via tubes or on foot, given Jelliquids tend live on small islands), etc. The job they choose can be anything, almost everything is payed the same, safe for life-saving jobs (doctors, firefighters etc). So almost every individual of course chooses their job based on their skills and/or interests. As a result, most are very happy with their jobs, safe for the occasionnal individuals who haven't found their calling yet.
All this may make Jelliquid society almost like an utopia- and in some ways it is, but: firstly, the overindustralization is a big problem, and is hard to stop- not out of greed, but more of because of pride. Indeed, powerful Jelliquids can be egocentric and not value nature, regardless of money not being important in their culture. And secondly, Jelliquids being a game, there's antagonists that tend to more or less severely ruin individuals' lives. Most of said antagonists and bullies are NPCs, that were made to mirror bad treatment the in-universe dev, Papié, suffered from by being a trans man. So despite all the positive things in the Jelliquids world, depression, anxiety and the like are still very much a thing. Thankfully, the Jelliquid dateable characters being sentient, a player's presence and hopefully affection tends to make their lives significantly better.
