Sure, though my language is probably too harsh maybe? The game is still good, and it's still a good time playing it. There's no real way to avoid spoilers when talking about the ending, but I suppose I'll try to be as vague as possible. I'm just writing some more filler text here so maybe the spoilery bits are hidden by the expand prompt, even though it seems the expand prompt only shows up if you're logged in, so apologies to those who aren't logged in and hopefully you don't read the SPOILERS AHEAD.
Is that enough space to hide it? I guess I'll see. Okay, so, about the ending. The whole point is to work towards this 'prime timeline' where everything and everyone is okay. And like, yeah, that's a good thing. It SHOULD be the goal to make everything work out for everyone, that part I have no issues with. The part I don't like is how it absolutely obliterates one of the best parts of the game, which is the character development. You go back to the point where nothing has happened yet, and then the game ends and rushes into a romance over the span of a few minutes, that took a month's worth of in-game time to work itself out. Sure, the feelings were already there, but it's just so much... lesser this way.
I know that, in a game with branching paths like this, it's very common to have a canon route. But this just feels like the worst of both worlds. The non-canon routes are cheapened by the way the true ending is handled, and the true ending itself doesn't benefit from the development over the course of the game.
In my opinion, a better way to handle it would be to rework it all so that you're taken back to, say, day 20, or at least around there. To the point where most of the development happened, and from there you can give everyone a proper ending and epilogue. Alternatively, you can have the convergence point be after the vacation, though obviously you'd have to rework a TON, including a certain bit where you get the... Virgo medal? I think that's the one, at the very end. That way, every branch can have the possibility of existing in every timeline, but once you've been through them all, you get the prize at the end. I know the 'point' of the game is to settle on one timeline where the good thing happens, and that it'll happen that way now in future loops, but it just feels bad currently.
Outside of the character development, I just wonder why Dave is even doing this to start with. Why is it him? Why does him doing what he does in the 'prime timeline' matter at all for what the mastermind does? He doesn't even know the final password, and even if he knew it, it wouldn't have mattered. It's not the end of the world but it does feel a little awkward. (And I admit maybe I missed something that explains that but it just feels weird to me how that goes down.)
This post on reddit also echoes my same feelings about the way the true ending went down, with a little bit more spoilers.
I'll also add that I'm not in the discord and I haven't been following your news or anything really after this beta build, so I have no idea what you've changed or what you planned to do after this specific moment the game is in right now. I recognize that my bit above about a better way to handle it would be a massive undertaking at this point, and heck, maybe you simply disagree with my opinion. I'm sure other people do. I absolutely don't expect you to do anything extra, change anything, go about revising things just because I said I didn't like it. I just wanted to express how I felt about things. Short version: Character development, good. The way the ending handles that, not good.
