Our game has been created in Linux, it is free under the GPLv3 license, and has been created with Godot Engine!
And it has Linux builds, of course!
It is a fishing game! You control the bait with only one button. And you want only a certain fish... and it appears only one time! Patience, skill and beautiful art! :D
Please take a look :)

In fact, we encourage you to download and check the native builds. The WebGL (sometimes) gives weird things with the music!
