I don't know if the delay is justified or not, but I know that (update or not) April will be the last month I will be subscribing my 10$ tier Patreon.
As a SW developer I can say that it isn't a professional way to work. Especially when, according to lostraven declarations, the delay is due to pedantic reviews on dialogues. Well: if the program crashes, the delay is justified, otherwise you deliver the game as it is, in order to meet the due date, and THEN you release minor patches with the updated dialogues.
PS: I don't even read those endless dialogues. They are TOO many, compared to the actual game component, making TT an unbalanced game. Summertime Saga, for example, has an acceptable dialogues-game balance.
