Any possibility of making a version that's either native to Linux or can be run through a browser? I'd like to try 0.5, but since I'm using Linux on both desktop and laptop (and I'm one of the oddballs who doesn't have a smartphone), my best option is to use WINE to run the Windows version, which runs but has no text on buttons and menus.
A browser compatible version would probably be easier, but does make it easier for some jackass to just post on a website somewhere and claim credit or some such BS, so I can see you being hesitant to opt for that method.
And sadly, I have no idea how difficult it would be to create a linux-compatible release through Unity. (If it's a matter of not knowing what the options are, a .deb file is probably easiest to work with for most people - it's an installer file for debian based Linux distros, which is a good chunk of the Linux userbase, and includes some of the more popular, less technical distros.
