Some sorta spoiler here
The first ending I got was the one in which Silas sadly sacrificed himself to save the mc, I was too sad to let this be the memory I had left and I also wanted to save him so I replayed and happily got the romantic ending, I had the intention of trying the other left but. no. dan. way. in. hell, what if it's also sad? lol
I love the fact that I had so many choices, I was a little bit confused about what some of them meant, but I eventually tried one and if it wasn't what I wanted to say then I went back and chose another one that best fit what I wanted to say, so no big problem (it's probably because they were similar or because I'm not really fluent in English). I also like that Silas is a pretty well written character, the only thing that I didn't really enjoy was that the game is short, and I didn't feel like I could properly develop my relationship with Silas, my thoughts and all that would've led me to a certain ending instead of another. Of course, with this I'm not saying that This, My Soul is a game that doesn't make you feel like you're living it in first person, isn't engaging or something like that, but it doesn't give me enough time. And also of course I'm not saying that it should be 10 hours long but something like 5 hours (roughly, depending on the ending, but I guess the ending wouldn't last long) would've been better, considering my 2 hours experience when I first played. But I know that it takes a lot of time and effort to create a game like this already is, and I really appreciate and admire your work. Also another thing, I think the mc's sprite shouldn't be there because some players might not resemble it, and this in some cases could ruin the experience (this wasn't the case with me because I resemble the sprite a lot).
Thank you for creating this game, it was a really nice and emotional story, I haven't found many like this and I'm happy I played.
Overall I would give it an 8/10.
