I would love if u added in bad endings and/or more endings in general.
Stuff having (lots of) choices/choices that can lead to different endings/types of endings and/or consequences I find awesome (more often than not).
So basically, YES, I would love for you guys to add in bad endings/dark(er) outcomes and stuff to the game! :)
And/or like I said, just some different endings/kinds of endings (and routes) more generally.
I think different choices leading to different things can be a really cool and good thing.
And even though the MC/protag was sent back in time to make thigs better, that doesn't mean he always will.
The butterfly effect (which sometimes even small choices and happenings can lead to big things. Time travel stuff can really play around this, and I can find it really interesting when they do, so it could be cool if this game did some as well in some way(s)), the result of ur choices and etc., can lead to both small and big things; good, bad, and everything in-between. And just because the MC may be trying to make good/better choices, doesn't always mean it will lead to good or better results.
Sometimes in trying to make better, instead of better outcomes/results, I could see it leading to bad and/or dark ones, or even worst ones.
I think it is realistic personally, for a game of this premise to have more dark, bad, and/or endings/outcomes/etc.
And I find it kind of weird personally how so against some people to having more endings/outcomes and/or to have more dark endings/outcomes. It is not thematically disconnected or incosistent at all. Plenty of time travel stuff will have people trying to better and fix things, and things going wrong, or them having to try over and over again in order to fix things/some thngs and/or to make things better/some things better. Or some paths leading to better or worst or etc. endings/outcomes.
Like, I think Steins; Gate is a very good example of this.
Anyways, like I said before, would love more endings/outcomes/etc.
