First I'm not a donator so I do not care when the update will release, if the dev does , I will always appreciate him. But in the side if donators, I don't know how hard will take him so long to do the update.
Let me say some examples: Willy D , apocalypse, Angelica' temptation and so on. None of them will use over 3 months to release a update. And also, each update they release is always bigger then Anna.
Or you can find one game which is much like anna: lida's adventure, but in my opinion lida is more bigger then Anna. And the dev also post the update in 3 months. And now he is sick, but remember, his last update is May.
So I want to say that, the dev should respect the donators and do not waste their time and money. You are becoming more and more like the defenestration's dev: delay, sorry , and delay again. It is sad and arrogant.
You can learn the way apocalypse and angelica: post the game update to the donators first, and share to gamers for free but they must wait one month. The hard work is never you excuse. Frankly, you work does not worth 100 days, I can see a lot of great works in the fan art area. So cut the shit excuse and do some value works for you donators, or you will get the FreshMulan's problem.
