this game should be already finished, the content is not much in every update (at least before wasnt and i been following the game since 4-3 years ago) is not that hard to code a game like this actually, its very simple... theres no mechanic or anything that you can say "oh well, i need to make this mechanic of the game and make it work with all the other stuff i have" which is basically none, the drawing is not perfection, is good but you cant say its great but thats my opinion, and the story? is simple af.. theres no excuse, theres a few developers that make this kind of game, they already finished them and they are doing a second game or even a third game and their teams are not even big, 4-10 person at most
and if hes doing the game alone (which i dont believe he does...) with those 9k a month he gets from patreon he could hire some people to increase the frequency of the updates... but we know why he doesnt do that..
