Godot makes it easy to export to Linux and I'm sure it's still true that feedback from Linux users is better even in terms of finding bugs as mentioned in this interview with Croteam in 2015:
> The feedback from Linux gamers is great – they seem really happy that we’re supporting the platform and they are a huge help in finding bugs. Often, bugs that are initially reported as Linux specific turn out to be issues in all version of the game, it just sometimes happens that it’s easier to reproduce on some platforms. So, yeah – we’ll definitely keep on supporting Linux in the future.
