Loved this. Got the ending with Ayame the first time, then I worked on getting the other endings...
...except for the "Forced One". I only went with the option for it for the gallery images and went straight back to the title before it could even get to that ending. All I've read is that it's surprisingly dark, and if Undertale is anything to go by sometimes going for seeing everything isn't always worth it.
Still, I enjoyed the game and it's surprisingly well thought out story. Only criticisms I have are ones that have been mentioned already. Mainly the writing for the narration and dialogue and the lack of lively animation.
Got the Patreon version, and the extra ending and scenes are worth it for the small-ish amount you pledge for it.
Very well done! ;)
