About this game
Peacequarium is a cozy idle aquarium simulator that you can resize and keep anywhere on your screen while you do other things, or you can play in full screen windowed mode! You can set the game window to always be in front or allow it to be covered by other windows when you need more screen space to focus on your tasks. So whether you're studying, preparing a budget, or driving your train through the zombie apocalypse in Choo Choo Survivor, or just doing mind numbing tax paper work, you'll always be able to look at your cute fish and feel so much better.
A hundred fish to discover, grow, keep or sell. Fish are categorised common, rare, epic and legendary with different values and earning rates. You can endlessly upgrade each species of fish to increase value and earning per second and you can apply fun traits to your fish from your Steam inventory that make them more unique and beneficial to your gameplay. There are also special glowing fish for each species that drop into your Steam inventory from time to time and you can spawn these into your tanks, whenever you want, for more unique fish and for their triple value and earning per second vs their normal species counterpart.
Twitch Integration! Viewers can spawn cute snails and turtles that generate a little bit of money for 60 seconds with the command !snail and !turtle. Up to five mini auto feeder submarines can be summoned with the command !sub
Steam Inventory Integration! You'll regularly receive gift boxes, fun fish traits, and unique glowing fish that you can use in game for extra fun and rewards.
Lots of cool upgrades to purchase; a can of worms that enables you to summon wholesome buffs, increased earnings upgrade, increased feed power upgrade, a submarine that auto feeds your active aquarium, multiple aquariums and capacity upgrades, lovely backgrounds, and calming colour schemes!
It's up to you if you want to play actively or passively. If you are active then you'll get the gold fever fish, super feed, and the treasure chest that gives you tons of money! If you play passively then your fish earn every second and even when the game is shut down so you'll never be disappointed!
Don't forget to pet the husky!

Star Journey
Hi everyone,I'm making great progress on a new game where you are a starship captain with a crew. You can also modify and build starships!Travel a living starmap of claimed worlds, hostile fleets, neutral powers, spaceports, unexplored systems, and dangerous anomalies. Take command from inside your ship: pilot through space, raise shields, fire torpedoes, manage power, repair hull damage, consult your officers, and decide where your crew goes next.The frontier is full of incidents waiting for a captain’s judgment. Rescue stranded survey teams, investigate suspicious distress beacons, uncover ancient probes, stabilize unstable anomalies, make first contact with new civilizations, and decide whether defecting enemy captains deserve asylum. Some missions lead to diplomacy. Some lead to discovery. Some are traps.Beyond the bridge, the war continues. Factions move fleets, defend homeworlds, patrol borders, capture systems, repair damaged ships, and lose captains. Your actions leave a persistent mark: ships are damaged or destroyed, passengers come aboard, prisoners are held, discoveries are recorded, and explored systems remain explored.If this sounds interesting to you then please wishlist Star Journey!Best Regards,GTGDRead full article on Community Announcements (Gamer To Game Developer)AnnouncementsOfficial
