I'm quite enjoying this story! It has a really interesting and original concept that doesn't feel like it's just a copy of what a bunch of other IFs are already doing. Your writing style is engaging and though there's a few spelling mistakes and incorrect phrases, I'm still thoroughly invested in the world you've created.
... and that sex scene near the start of the game (that dictates your sexuality?). Whoa. Hot! Very *chef's kiss* - you have a talent for writing smut and I can't wait to see more. :D :D
Three things (?) I thought I'd mention.
First, although the Warden being (fake) blind is an awesome concept, it seems hard to believe anyone would actually believe the Warden could kill ANY monster blind (as they think he is) when he can't even get around the city blind, or at least struggles to. If the Warden used some sort of magical means (like a sonar/echo-locating spell) to assist him through the city, thus having no issue being misdirected or bumping into things, people would just assume he uses magic to 'see', and that he uses that same magic to help him 'see' while fighting monsters, and so wouldn't question his blindness at all. THEN it would actually be alarming for the Warden if anyone seriously hinted he was faking it, especially if they could sense the magic rolling off the Warden - so much so that the Warden might be seriously on edge around that person.
As it currently is I'm surprised everyone seeing him be assisted or randomly stumbling into walls isn't seriously doubting how he could possibly hit anything, let alone kill a formidable monster. lol
Second, I'm playing a stoic/cold/closed yet confident (including with sex) male character, but there are no real "flirt" options that fit such a personality. one is shy, one is bold, and the third is sort of jumpy and nervous. As a result I only have the choice to either not flirt at all and miss out on the ROs (which sucks cos MC is horny and secretly wants that good lovin lol), or to break character just to get one of them. I realize it's a lot to ask, but is there any chance you could add an option that specifies an unexpected/unwanted sexual attraction, or sexual tension, indicating our MC is interested in the person despite themselves?
Lastly, in the scene where you're in Hestia's house, just before she joins your expedition, would it be possible to add an option not to react at all when you learn of the spirits crowding around your character, or pretend it doesn't bother you even if it secretly does? Both the existing options or excitement or panicking are a little dramatic if roleplaying a stoic/cold character (funny though - especially the panicking one!).
Anyway, hopefully you read this far (if so, thanks for bearing with me). All in all this is a really great start so far, and I'm looking forward to all future updates! :)
EDIT: OH! And one thing I forgot to mention, I LOVE the character customization. I don't think I've ever gotten an option for nipple or genital piercings, but I'm here for it (and chose them, of course! lol). <3
