Comment sections are not just for blanket outpourings of love and support for whatever the dev creates. Creatives can't adequately grow and learn without criticism. Not sure where you're getting harrassment from, but I've not seen it on this page and have read every critical review posted so far (even the ones I've had to google translate).
Also, (ignoring that the content warnings were initially hidden so the author could have their gotcha moment) I sort of mentioned this in a previous comment, but suicide in games rarely bothers me (as someone who has attempted and almost didn't survive, since we're sharing). When written well, it can even be incredibly cathartic. For example,there's an interactive fiction game on steam in which you can choose to have your MC struggle with suicidal thoughts. The difference is that the author of that game either struggled with similar thoughts themselves or actually did research, as everything came across as very realistic and relatable to me. It wasn't pulled out as some ending plot twist, but was included as something the MC grappled with alongside their myriad other struggles. The absolute best part is that it's completely optional. All that to say, suicide in media isn't a problem for me when written about knowledgeably and respectfully.
And a content warning for suicide (when one can actually find it) doesn't excuse the writer from criticism if it is written poorly.
Edit: Deferring to and agree with Miru's critique of the plot.
