I don't know why people keep complaining and scolding the creator, it was clearly stated that this is the prologue and it was 3 year of work and it is free. But there won't be update until the final version of the game is done, which will be paid. So if the prologue only needed 3 year I can imagine the full game will be twice or thrice of that time. Let's just wait and act like intelligent human beings.

Did you ever thought about him being bored about all those when/where questions and thats why he doesn't answer? It was clearly stated that there won't be any more update for this cuz he is working on the full game, which is not 1-2 year to make. Even an experienced big studio is working on a game for 5+ years and however this game is by far not that big BUT THERE IS ONLY 1 PERSON HERE. So think about it and read carefully what he said before complaining. People should learn to read the ingame notifications and patreon/discord/website ones of a developer before scolding and asking stupid questions.
