Quit coping dude. They both encouraged the PC to date other women. These are the consequences of hiring a lesbian woman to write a male fantasy.well - what a bummer to notice that actions have consequences. Fooling around with too many girls? well, then some of them will get upset. That's how all 3 games of MrDots are.
(Our next game will be a harem game though).
And you don't need to fear to lose your savegame based on past decisions - you always can toggle each girl's path on and off using the tablet -> choose the girl you want on the right, and click the red heart. It will turn grey if path is closed.
That way you can toggle each path on and off like you want, and you don't need several full playthrough.
Once you encounter a scene you messed up, just scroll back to before that scene starts, toggle girl like you want, and everything is fine.
When done, load your old save and play the other path - so you can experience both paths, just not ending harem like.
How about actually writing something yourselves instead of outsourcing it to random people in the Internet.
