Update on that. I downloaded it and gave it a try and sure enough, the sound doesn't work. Looks like they didn't perform the due diligence of testing. I'm currently downloading the windows executable to try with my system install of Wine.

My rule is, if it is proprietary software, I don't fiddle with it. I dislike Playdead for making me break my rule.

uh, citation needed? You'd at least have to specify whether you mean "offered for sale" or "purchased by users", because I suspect a big chunk of game sales volume comes from AAA games which are probably going to be native ports.

Negative, this is the first one.

The games I tried on Linux so far, have been really high-quality ports. I know icculus did quite a few of them. I haven't played that many, though.

What is it with that idea that somehow "Wine isn't native"? It's not an emulator and it's not a virtual machine. It runs the native executables and provides a couple of Windows-like folders, DLLs, a "registry", environment variables etc. What's not to like? Sure, would be neat if the game devs had a dedicated Linux build target working with /usr/lib/ etc. paths but -- does any gamer care? As long as Wine is as hidden and stable and packaged in the background as Transgaming's Cider (try the three GTA 3 games on Mac from the App Store -- awesome smooth gaming! -- granted they're quite old) I don't see a problem for the gamer. And the devs are free to concentrate on their games and creative instead of headaches with painful "native porting" code issues.
