I have recently started dualbooting Linux Mint. It's absolutely incredible, would recommend, but that's not the point. What I'm here to say is how close blockland is to native Linux support, why it should be added, and how well it currently works on wine
Blockland currently works on Windows and Mac. The thing that's important for Linux support is that it already works on Mac, which is a system based off of Darwin which is based off of BSD which Unix-Like. Linux is Unix-like as well, meaning their systems work quite similarly. For example, the terminal program nano will work both on Mac and Linux, and almost any other Unix-based OS. This, in short, means that Blockland is pretty close to native Linux support.
Why should Native Linux support be added? You've mentioned it works well in wine! Well, first of all, steam. Steam does not even allow the
installation of programs where the developer has not specified that it works on the OS you are running. This means anyone who's bought the game on Steam cannot download Blockland off of Steam. Secondly is that it detours a Linux user from buying the game off the Blockland website. There's only a chance that any old game you find will even work in Wine, and if it does work, it's very likely that it will be glitchy or some features won't work. There's no guarantee the game will be enjoyable on their system, and they're probably not going to want to throw money at it until it gets native support. Lastly, with SteamOS, native Linux support would mean the ability for people to play Blockland on Steam Machines, which have the potential to be huge.
Now, I want to show some pictures of Blockland running in wine. All I did was head to
https://www.winehq.org/download/ubuntu and press "click this link to install the wine1.6 package.". I know it says Ubuntu, but it worked for me on Mint as well, and I'd imagine it'd work on any distro with apt-get. Before I talk any sooner, here's some screenshots of blockland running through wine, in Linux Mint 17.2:
VV Fullscreen mode, Max Shaders VV
VV Windowed mode. Max Shaders VV
As you can see, it works with fullscreen mode, shaders, and everything. I was expected it to barely work 1/2 the time in windowed mode and have no shaders, but this blew me away. Would it really be that hard to implement native support?
