Little Glass World



Welcome to your tiny underwater world!

In this cozy idle game, you create a living ecosystem inside a glass jar filled with water.

Click to generate bubbles, buy cute fish and aquatic creatures, and watch your jar slowly come to life.

MY FISH DIED?!?

Yes, that's the circle of life. But you can always buy new ones.

I can't even clean em out

OK, this should actually work.

Really like the fact that you made the game without any game engine and created it using HTML, Javascript, Vanilla CSS. 

I'm not usually a fan a clicker games but I enjoyed this.

I'm glad to hear that, thank you.

Not a fan of the stars, I feel like its a lot of clutter when the focus should be on the fish. I really didn't like the strobing color effects though, feels like the opposite of a relaxing clicker game

Yes, I understand that. I wanted to somehow add more "fun" to the game, but that was a bit too much. But it was fun making the game, and it was only a few days for the game jam.

Very creative take on clicker games and I love the art.

Thanks, I did that at a game jam in a few days.
