I played and it's good. The models are amazing, the sandbox is not bad. History still has a lot to grow and I am looking forward to it.
Now a few words for DEV.
1 ° - First of all, I saw that you intend to give space to your supporters and fans, this is good. But I advise you to restrict this space to simpler things as has been said here before, like hair things, updating to a specific LI, more space for a specific LI, and lighter fetish (things like socks, footjob ... and even so make it optional). Because many people agree with me, when you leave this "space" too wide, some people (whether intentional or not) tend to lose some weird shit, and end up screwing the game. We have seen many cases of games with the potential to become one of the biggest, ending in a mediocre game by introducing some bizarre things where it restricts its audience to a small part.
2 ° - The lesbianism thing, the game is yours and you make it what you like, but I also advise making these scenes optional (when I say optional is to make it not happen, not something like the MC closes his eyes to not see and even so it happens), especially if the MC is not involved in them, it may not be that damn tag, but many people also don't like it and can cause the same impression (I don't even like to quote that tag ... hahaha).
3 ° - About the sandbox, for me this type of game is not a problem, only and boring when you have a lot of grind, and you have to be doing the same things infinitely until you get something. I played in easy mode, so I didn't have too much trouble with that, I would only advise you to stop some scenes from repeating, like watching TV with Auntie. You can create a gallery for those who want to review the content have this option. In addition, I saw no problem.
4 - Tips system. I don't know if I'm the one who is really stupid, but I didn't really like the current one, it would be better to make it a little clearer what to do to get some things, like the key I found the pointer on the screen. Although now there’s not much to do, this is fine, but later on I don’t really know what you want, but it would be nice to have a clearer hint system, like, "Aunt must have a key somewhere" or simpler things. But it could also be just me who didn't get it right ... hahaha
5 ° - I also saw that you say that you put some things with Tia to have some sexual content in the first release. Well, in my opinion I think that is unnecessary, many of the DEV's think that this is a requirement and end up putting something forced to give some sexual content, often more disturbing than helping, because often they want to show what is ahead but they want to leave an easy path for the MC and end up putting something that is unpleasant (voyer, "3 letters"). So I would advise you not to rush things to make fun of sexual content, if the story is good you will not have too many complaints. I'm not saying this is the case here, but you don't need to have a lot of sexual content with each update, especially the first few. Take your time and tell us the story you plan to tell us.
I believe that was what I had to say after testing your game. I really liked it and I'm looking forward to the next update, I continued with the excellent work and if possible think about what I said above.
Good luck DEV and thanks for your work.
