Seems like there's only really one interaction she has at the moment, and there's no apparent way to get more points other than just waiting. Probably needs some kind of rewards for interacting.
There's not much else to talk about for the current state of the game, but as far as the idea goes I'm not very keen on it. The kinds of apps that offer this kind of functionality that I know of are either "cosy games" like that one cat cafe game video on YouTube recently, pets that just crawl all over your screen (alternatively, chibi anime girls that walk around), or literal desktop strippers.
IMO, you either make it an R18 game (which should probably make for an interesting video later down the line) or expand on customization and interactions to make it into something like tamagotchi.
Frankly, it seems like an overcrowded genre to go for if you're not going to add significant changes to the formula because there's only so much screen space a weeb can allocate to things like this, and I've seen so many of these desktop idle games already. I've even seen NFT companies try something similar at conventions before.
It's also not going to be able to compete against gacha games like Azur Lane, Brown Dust or GFL2, and that's probably where the main audience wanting anime girl interactions lies in, because it already provides something similar to what you have here with a much higher quality, on top of having the rest of their respective games' gameplay and characters/story/etc. (Disclaimer: I don't play any of those games, but I know people who do and the clips they post sometimes are pretty insane)
However, if you still want to make a game like this, then I'd actually recommend targeting the female demographics with anime men instead, because your only major competition in that department would probably be Love and Deepspace and that has been wildly successful.
Also it would be absurdly funny if you actually turned yourself/any of the team into a hot anime guy for it, you wouldn't even need to pay another voice actor to do the work.
