We are distributing the binary versions for Window, OSX and Linux (sort of) together with the source files, under the release/ folder.
The universal way to play games made through the LÖVE framework is to install your system's respective application (www.love2d.org) and execute it passing the *.love file by command line or by drag-and-drop. You can find the everknight.love file in the release/linux folder.
Follow the method above.
Just get the whole folder release/win32 and run EverKnight.exe.
Extract release/osx/EverKnight_osx.zip and install the app.
