This is a guide I wrote to help other Linux users play Blockland. There are a couple ways of doing this, however I chose to stick to using a GUI as much as possible for ease-of-use purposes (because we know that's what Linux is
all about.)
First, download the
windows installer for Blockland off blockland.us

Open up your Downloads folder and right click Blockland_Setup.exe and go to Properties. Check off "Allow this File to Execute"

Now open up Terminal and type
cd Downloads/
wine Blockland_Setup.exe

Now just follow the installer's instructions

Done installing!

Launch Blockland from desktop or from installer. Now just enter your key.

And you are done! I hope someone else found this guide useful.
