I had to choose Insaniquarium to analyze because I literally grew up with this game. Basically, Insaniquarium is a chaotic aquarium simulator where players feed fish, collect coins, and protect their tank from alien invasions.
The core mechanic revolves around players maintaining the tank and making sure the fish don’t die from starvation or being eaten by aliens. Players have to feed the fish to keep them alive while collecting coins and upgrading whenever possible to be able to pit against stronger aliens that take longer to kill. This creates a constant cycle of attention management. If you focus too much on collecting coins, the fish might starve and if you focus too much on feeding, you might miss valuable currency that enables you to upgrade food or buy more different types of fish with better abilities. Players also have to watch out for alien attackers warping into the tank to eat the fish, which forces players to divert attention to frantic mouse-clicking combat to protect the aquatic ecosystem. These aliens get stronger as players progress in the levels and so choosing which different types of fish to keep in your tank becomes a strategy on its own to last through tougher alien attacks.
The game combines the mechanics of time pressure, prioritization, combat, progression, resource management and increasing complexity to form a dynamic for the player that I would describe in a way as mastering our multitasking skills. I remember I used to get anxiety over when the alien might attack and eat my fish but now I feel like I enter a flow state while going through my aquarium priorities and this pacing and satisfaction of juggling many things at once keeping fish alive, upgrading the tank, collect coins, fight the aliens makes it really fun and rewarding.
