Always nice to see your posts!!
For the Steam dilemma, I guess going for DLC is the best option? Other games have done similar things. I would try to delve a bit deeper on why some games are being banned for their lewd content. House Party is an incredibly erotic game with explicit nudity & Sex and it's still there going strong. Mind you, it has been one of the most successful lewd games, so there's that. But maybe you can find more reasons as to why they were banned and get a better idea of what position you're in. For example, I know for a fact that some lewd games in certain platforms have been banned not strictly because of their content (thought that was the excuse), but because the developer was problematic to put it in a way, and the platform didn't want to associate with them, not the game specifically. Just an example, but I mean to illustrate that sometimes there are external reasons, maybe you find something that can help you.
Other than that, the new ideas are great. I like how you're going for the pixel art fully. It looks super good. I do have to say that I like Chiharu's outfit A LOT more in the previous version. It's much more colorful, more stylish, with more personality imo. Overall the new models are super great.
Now in terms of game design, you've got some interesting choices there.
I like that you got rid of the static times. It's good for certain games I guess, and in the early game it works well, but in terms of gameplay at lot of times you just end up clicking through stages endlessly while you're trying to get something you want. It devolves into "click this things to do", "Click pass time", repeat until you get what you want. It was fine for a short game, but as you play more and you get to the "end game" it starts feeling repetitive. idk, it's just a balance that I've found hard to maintain in my own games. A real time system obviously feels much more dynamic. It's harder to code due to navs and pathing and such, but the advantages are great. Being able to walk through the Onsen while the day advances will create a much better connection to the player. It will feel more alive, like you're actually working there and not just assigning tasks in a certain order. So yeah I really support this decision xd.
The other thing you showed is also interesting. I understood that you're going for a kind of a gardening / building mechanic, placing plants, etc. I'm guessing the inventory system will come into play here. I didn't expect this here but it is much welcome! It can be a really good decision, it might open up a lot of new gameplay mechanics options for you in the future.
Overall, I feel like you're making the whole gameplay have a much more dynamic flow. The real time passing, inventory systems, gardening / building, etc. It ties much better to what you said (if i remember correctly) about wanting to let the player leave the Onsen, go to town, etc. Doing it this way is much more effective for that goal.
Sorry for the long post xd but I really enjoy game design and chatting about it!
BTW is your first language spanish? Cause I saw in one photo it was all spanish (it's mine too heh)
