Our game has been created in Linux, it is free under the GPLv3 license, and has been created with Godot Engine!
We used the 3.1 version for the first time, loved the new Animation Editor and so on.
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.
Long live Godot!
