This comment just about sums up my thoughts. I don't have many new points to add since this comment says it all already, but I wanted to say something anyways to express my support and admiration for this game.
I highly enjoyed the experience of playing it, especially because I sometimes like to voice non-voiced games for myself while I'm playing them, and Myosotis was among my favorite to read--both for the text itself but also the emotions it made me feel while voicing the lines. I felt for all of the characters--particularly for the MC, given what happens to them.
LIGHT SPOILERS BELOW:
As penelopticon has already put very eloquently, there is a lot to admire in this game but also a good number of things I would consider flaws or caused me to feel a bit disappointed and unsatisfied--with the biggest of them being a bunch of tiny unaddressed story points that ultimately build up into a sensation of "Okay but why?" or "Really? That's it? That's why?" that I just couldn't ignore. I will admit to feeling like the ending was rushed with a good number of details just never addressed. Personally, the one I found most unsatisfying one was the aftermath for MC in general; their body is seemingly never recovered and their death is hardly ever mentioned. I understand if the story was never really meant to be about about them, but I found it difficult to suspend my disbelief given that there is a whole corpse rotting in a cabinet as well as disheartening to feel like they were swept under the rug--especially given how MC themselves can feel incredibly disregarded or made to feel insignificant about their own death.
(By the by, penelopticon, I also theorized that Jude's whole deal was something like you described; I was so ready for him to be bound to some demonic entity or something like that and paying an incredibly high blood price for a desperate wish or something other LOL I was like "oh god watch this be something crazy, i've seen enough monkey paws go wrong". Unrelated, but I will say that I am mildly proud for quickly realizing what the deal was with Jude and Ethan when I saw how similar they looked to each other.)
SPOILERS END
That said, it is understandable if some things had to go in order to make deadlines or to make for a tighter, more concise story. Perhaps there simply wasn't time or space to get into all of that. Regardless, the presentation, writing and editing, and soundtrack definitely still shine a lot and Myosotis is a title that will stay with me for a while, much like one Very Sweet Not John Doe <3
