I actually did ask for proofreaders to help me, but after asking for 30 or so people, and majority didn't actually do it. I'm tired of waiting and asking, so I released it as it is. Well, that's volunteer for you. ^^; It's really hard to find dedicated proofreaders >__<'''
For Loil:
He is! XD I created him with a joker role in mind. Crazy, twisted, scary, but funny...like a clown. While he isn't the main conflict, he's the source for most of them.
For Anon's ending:
I wrote a little bit of this in the gallery section, but I supposed I can extend it here. Anon is a personification of someone with no personality/identity, or at least he believed that much. He basically wears personality like wearing clothes. Any personality you saw in the game, be it playful trickster or emotionless/uncaring are all personalities that he borrows. He can easily wear and discharge them as he pleased.
By the end of story, he basically realized that it doesn't matter what identity/personality he wore, Essi needed him, and what the most important is---he needed her. There are multiple reasons as to why he returned to wearing the playful trickster persona back at the end. First, he believes it was the personality that made him get close to Essi in the first place and the personality Essi most used to. The other reason is he has been using this personality for so long that he stuck with it.
In any case, there's more to his past told in Oure's path. And you can kinda tell what kind of damage Scid did to this boy mentality. Anon original personality is something else. The current Anon was born thanks to Scid's experiment.
Whew, that was a lot harder to explain than I thought ^^;;;
For ending 7:
Yup, locked by Loil. This is hinted in the internet conversation earlier on.
