Played this quite a bit today, had great fun, really fantastic underrated game, though I would add the following as feedback:
1) It is annoying that when you unlock a room, it moves onwards to the next day. Can you at least allow me to look around in the mental room before you kick me out? I know every room gets a sort of introduction, but i'd like to walk around and interact with the things before you toss my unceremoniously out.
2) This will of course change as the game progresses, but there are still parts that say NOT IMPLEMENTED in the first "zone" in the mental world, which is a bit jarring to see when you are playing.
3) I would love there to be some sort of .. notification? Maybe a glowing lamp of some sort? That indicates you can do *something* in one of the rooms you unlocked. The latter part of the first room was a lot of going to every single interactable spot and interacting with it to double check there wasn't something new, because the game frankly has a real hard time indicating what's new at times. For a little while I even thought I had somehow softlocked the game, but it turned out there was just one interactable I hadn't tried in another room. This could be fixed, as mentioned, by some sort of signal outside the room that there is something new to do.
4) In terms of progression, I thought the corruption sorta whiplashed at times. At first she only really allows groping, but then there were events where you had full on sex (with the .. flesh doll?) which seemed like it very quickly escalated, but then it goes right back to not wanting to even be touched or kiss.
5) I agree with some reviews that this game is very slow to "unlock" actual erotic content, but I think that's the charm with this game. I would however council that towards the middle-end of chapter 1 and the first hubworld room (whatever you want to call it) there should be more signs of corruption? Dare one suggest something so incredibly lewd as kissing? It would just be nice if there was a bit more feeling to it. Also, I have to wonder what exactly the plan with the overall game is. How long is this "low" corruption level going to be maintained, because I think I put in like.. 5 hours (skipping some text, sorry) and I had only really seen semi-lewd content when the game decided it wanted to really mess with the heroines head, and not something as a part of her corruption progression.
6) Speaking of the length of the game.. I think if I was the author, I would maybe dedicate an update to just trimming the amount of text, not because there is necessarily too much of it, but because the more content is added ontop, the more "bottom" heavy the story is going to be. Like there is going to be a lot of text between you and whatever new stuff is added.
Anyway, those were my thoughts, great game, looking forward to seeing it updated.
