Cozy Games Today: December 15th, 2025

Peacequarium
Peacequarium is an idle sim that puts a charming aquarium on your desktop to keep you company. Grow, keep, or sell over 100 fish types across different rarities. Use earnings to buy upgrades and if you want to be social, link up to Twitch to allow viewers to spawn snails and turtles to give you extra income for a limited time.
The Son of Art
The Son of Art is an adventure exploration that takes you on a journey through the inner worlds of four 20th-century artists. Dive into the works of Picasso, Malevich, Magritte, and Mondrian to feel their art on another level and solve puzzles related to their works.


Penny for Your Potion
Penny for Your Potion is a shop sim. You’ll grow a garden of ingredients and use the yield to brew up potions to sell in your shop. With a leveling and skill tree system, you can improve your game. Boasting over 20-30 hours of gameplay, you’ll have a lot of time to get to know the locals and to beat out your biggest competitor.
