Good for you. I was about to buy it despite preferring Linux, but seeing all these comments on HN convinced me to save my money for when the developer releases a native version.
The developer's website [1] says that it uses OpenFL [2], which advertises itself as "an exciting cross-platform framework that targets Windows, Mac, Linux, iOS, Android, BlackBerry, Flash and HTML5."
He's said he hopes to support it, but supporting multiple platforms can be a tall order for a single game developer, and not necessarily something they want to do. A quick visit to the Linux forums of almost any indie game that runs on Linux would put a lot of people off for life; there tend to be a lot of enraged users having trouble with their highly specific Gentoo configuration or whatever.
(For Mac ports, it's usually mostly people who insist on using MacOS 10.6.8 for religious reasons)
Maybe I have been lucky but I have never seen any such threads. The such threads I have seen have if anything been more polite than the average with more details and explanations (since Linux users are on the average more technical). Care to share any example?

So why no native Linux version then?
