this game is very much "what you see is what you get"
the story, or lack thereof, revolves solely around your older sister trying to earn money for your tuition via her onlyfans and you trying to earn enough money to be her top donor because apparently top donator will be awarded with something
the gameplay...... or lack thereof... is very simple money grind that's been done like billion times at this point. you go to some kind of work, progress bar fills painfully slow and you get some money, either more or less depending on rng. you then go use those eagles to support your sister's stream to either make her do horny shit or just donate to her stream.
now, i haven't tried this yet, and neither will i really attempt to try it, but i'm fairly sure the "just donate button" is pretty much just meant to be something you can quickly spam once you get infinite cash from one event and that's it. i would've loved for it if you had to use this to maybe make your sister's stream less popular (because less horny) and in that way actually have a way of winning this, but i'm quite positive it really doesn't matter and if you want to win you just have to use the money from that event. which means that the nothing you were already doing the entire time amounts to even less because it didn't even matter in the end. fun
sounds i'm gonna be honest, even tho i finished this game like 10 minutes ago, i can't say if there were any, either music or just background sounds
the art is fine, animation also, albeit there's not that much of anything. really, there's not that much to say about this. i kinda like the separate camera for her privates and face, that's nice thing i always enjoy, even if i would've preferred ability to make the secondary cam slightly larger.
all in all like 4.5/10? it is quite inoffensive, if maybe pointless in the end. the idea of someone having to earn cash to donate in stream of their beloved could really be done well, but this just does not do that, either conceptually in the way that this as incest just doesn't work or in execution, where there really isn't a game, when this has less actual gameplay than linear VN's
