Thanks for this comment, glad I scrolled down yesterday before giving the game a shot. I didn't even think to look at the content warnings with how cute the art and screenshots looked, but even then, you can never tell how well or poorly a writer is going to tackle sensitive subjects. As someone who's suffered from chronic depression and suicidal ideation for over a decade, playing this one to the end would've likely been like a kick to the teeth.
Plus, holding back a "good" ending in exchange for a ridiculous number of reviews from their player base seems extremely exploitative on the dev's part. Just to get their game to the top of the ratings lists, not on merit but through guilt-tripping their fans for Zilas' terrible ending(s). Absolutely disgusting.
(For reference, Our Life: Beginnings & Always currently has 4,908 reviews and is currently the most rated Otome game on Itchio. I don't think this dev wanting 5k reviews was a random number pull.)
