Heavy Spoilers!!
I played on Samuel's route until the big reveal on day two, and I let out an audible gasp in real life lol. Samuel being a woman took me by surprise to say the least, and honestly, it made me stop doing her route any further.
Don't get me wrong, I think having a character like Samuel is a wonderful and heartwarming touch in a visual novel, but it's definitely not for me.
I hope I don't come off as transphobe or any of the sorts, because that's definitely not the case. It's - like I said - not for me, is all :)
I might give it a go on the other routes, since what I've read so far was very enjoyable. Great VN! :D
