Sadly though, it still has the issue of having no sound on Linux, something I highlighted when I tested it recently. If anyone manages to get sound, please do share you solution in the comments. I would also advise against going fullscreen with CS2D, as that's also really quite buggy.
On top of that, the Steam release also still requires you to manually install some 32bit packages, which really is a nuisance. Thankfully, as I mentioned in the previous article, the top answer here solved it for me.
For the Steam release, I was really hoping they would have polished it some more, but for Linux gamers it's not a great experience right now. It is completely free though, so it's not like they're getting paid for this.
