Thanks for your feedback. You can read my previous answers, I have answered some of the points you raise. I have also a noob question hm. Can you explain me what is the "grind"? You're the second one to tell me about it but I didn't find any satisfactory explanations on the net.
By grind, people normally mean doing the same actions over and over to finally get a different result. In an RPG it would be pulling up 100 carrots per day for 10 days to get an item. Now not all grind is bad as long as their is something being shown for the grind that is useful and tangible to the game. Every day you pull carrots you get money, you are getting stronger/more fit, because you are more fit you can join a body building competition or the girls look at you differently. You are still grinding, but it has tangible effects and each time is worth something even if a minor thing, versus you had to do all 10 days to get 1 point in strength and you need 5 more to get to the next scene, it doesn't feel worth it.
Grinds
The keyhole, your character has to check the bathroom what might be 10 times before they think to do anything about the key in it. Logically he would know the key is there, and logically he would think either after the first few times that he could remove/hide it. Having to get to what I assume was sister in shower moaning twice before he thought to do it which for me was 10+ looking at a blocked keyhole was grindy.
Other "grinds" would be it seems you have to watch like 10 softporn to move on, and 10 bj to hard, it may have been story related but you can't tell.
Kissing the GF 5 to 10 to get to breasts which is 5 to 10, to get to ass which is 5 to 10, having to do the same thing 30 times to get anywhere is not something people like, a lot of it also is that it is the exact same text all the time, which makes it feel worse. So having the GF and the MC say the same things on try 1 and 5, then on 6 and 10, there feels like no progression or even no change, her saying something different, mother coming in, a nipple flick or whatever makes it seem more alive and less dig the same hole 10 times to get a carrot.
Some things make other things seem longer or grindier. I think the other part of the "grind" is that it is in its own full page, as I said before the game plays/loads slow, it isn't click and instant load, more like 1-2 seconds on click before the new thing shows, so a slow click to go there, then a slow click for the hole, then getting sent to kitchen which then you see ass and the end of character content for 10th time.
Some errors are the relationships rooms even if left as is say relationshipM's$room and relationshipS's$room rather than name or relationship.
Checking bathroom makes you go to "lunch" instead of breakfast so may want to fix that.
I think theo's house was named french.
As mentioned trophy and other whole sets of conversation are french, I didn't check the whole game though.
Small tips:
Either set up button pushes or allow player made keybinds to press them (1, 2 ,3 etc.), so you can use a number pad, or some other keyboard keybind to play the game, scrolling and clicking in a lot of html games can be hell on the wrist.
Try as hard as you can to keep each "page" without scrolling, unless of course new things happen. Again helps the player wrist and readability.
Also a small tutorial explaining what the white/blacked at the top means and what the stat bars mean/do/which side is what.
Sorry if this is a bit rambling, is kind of hard to explain a bunch of people's thoughts on something.
