Hmm, maybe that was the 1.0 build? Robo took all of those versions down to prevent mixups. I talked with them and apparently Ren’Py documentation says the Windows build should work for Linux, tho we haven’t tested it ourselves.
omg, really? i haven't really re-downloaded it to try it out, but i'll see later if so, i think it will work on linux if there is a .sh file, other than that i think not.
