I mean this game's pateron is at almost $11.5k a month is no longer just a hobby. A lot of the big games that's been in development for years also have pateron that more than enough to be a full time job. At least my experience with those is game has a lot of width, tons of varying content but the depth in each isn't as much but this kinda just set up it to last a very long time which make sense. A lot of people sign up supporting that game, a new game might not get as big following.I doubt this is keeping their bills paid. Game development is just a hobby/passion project for most devs and the majority don't make enough from steam/patreon to go full time. As for the MC not doing anything to change his life, hasn't he already done that? So far we've completely gone off course of the original timeline and the MC pretty much never had a single conversation with the most of the LI in the originally, and characters like Isabelle and Jackylin werent even at the school in the original timeline. Aside from just general school stuff which isn't interesting to watch I don't really see what else the mc can do
As for MC making a change he is but all we seeing is one side how he interact with girl. Nothing about how he interact with other people, his school work, and all that. Sure its not the most interesting but showing almost none of it feels weird too. Especially we got this whole stat system but you have almost no control actually building those stats and they all seem to become quiet pointless quiet early on. As for what MC can do well find a goal in life be good, what is his hobby? interest? likes? What does he want to go after high school? He is someone who regressed, should have much better idea of what his future goal is in life. (or at least a choice player can make or something) Even the mystery of his regression he is so passive about it.
Like for a story about someone regressing and redoing their life the MC is one hella of a blank slate which is probably one of setting where a blank slate mc does not work that well.
