Very good! I do have a suggestion though, that being that i think the absolute worst ending should be locked behind an option that is both dishonest *and* cruel. Because as of right now, the options are basically "be nice, but lie" or "be cruel but honest". Idk, maybe I'm missing the point of the game here.
The nice options really arent lies, youre choosing which option is the main character speaking his mind. Just because there is a bad option doesnt mean that is the "real" one and the nice one is him changing his personality. Even when choosing the nice options it becomes clear from the dialogue he's still speaking his mind and embarrassed about it, its just not purposefully pushing his own lifelong burdens onto someone he just met (which is objectively not a great thing to do). The way i read through it considering he had already had his window open for months and committed to a daily routine by the time you meet Button he is already a changed man and just doesnt realize it
Thank you for playing and I appreciate the suggestion!
-*SPOILERS BELOW*-
I take it that the choice you’re talking about is the one after the MC tells Button about death, where he chooses either to give a blunt, brutally honest response as to why the he chose Button (That she was the only option), or a comforting, sugar-coated response saying she looked cute and growing her would make him happy.
MC is never actively trying to be hurtful, he’s just missing out on social tact and experience, so I’m hesitant to hone in on the cruelty. The point of the more “cruel” answer is meant to show that he thinks being totally honest is the sensible to go, however he doesn’t recognise that, in delicate situations, this can be unintentionally hurtful.
I hope my explanation helps - I hardly get suggestions so I’m really grateful that you made the time to give one! I welcome more discussion on this or any more suggestions you may have :)
