2 years btw, if you don't have the intention of doing it at least change the text or remove mention of the free version entirely because it's starting to look like you've made it intentionally difficult to acquire to force people to buy it. If you don't want there to be a free version just say so, it'll look less shady.
Same with the compilation instructions, just remove them entirely, they can't be followed properly anymore. Just completely do away with the "it can be played for free" pretense, it's basically not true unless you essentially fix the bugs yourself.
