An excellent game featuring compelling, nuanced characters; a sophisticated narrative (and meta-narrative); and humor that doesn't overstay its welcome.
It seems to me that some world-building and story elements were overwrought or ballooned beyond the author's control. For example, I feel like Purity of Heart became a less and less coherent concept the more I saw of it, and the fact that cycling through episode at the end merely resulted in a cutscene that Simone could neither learn from nor retry was… underwhelming. I also found the ending unsatisfying; Simone's, Allouette's, and Mercy's stories all felt like they hadn't truly reached a conclusion. Frankly, it feels like the developer(s?) became impatient with how long development was taking and pushed to a conclusion before the story had fully ripened.
Also, hard mode was too easy in my opinion. The only times I was challenged by the combat were my first foray into the deep Dark Forest (which I attempted and completed without Lasca—oops) and the fight against Canasta during the first iteration of the Final Battle. I don't really expect to be challenged by RPGMaker games after how much time I've spent playing Sierra Lee's, so I was pleased to find any challenge at all, but… I don't know, maybe that feedback will be useful to you for the next game.
Still, playing this (and Quantum Entanglement, which I played immediately before this) was the most fun I've had playing a video game in… years, I suppose. Thank you for that.
