I won't go so far as to trash this game as this seems to be one of the first ventures for the dev but this just needs a ton more work, at least for me
From the parts I have played, the writing/dialogue wasn't as grammatically bad as I was expecting it to be and the animations were actually very fluid, albeit the shot from the back of her walking in the treadmill had her triceps clipping her shoulder
In general, Kasie is attractive but all renders are rather 2 dimensional. Details are kinda flat and make it hard to show facial emotion. Younger brothers are supposed to be at least closer to the same age as Kasie but have the bodies of 10 year olds, heads smaller than that of a baby, and the behavior of 8 year olds. Seeing Kasie and the MC side by side at the gym was rather off-putting. MC was just downsized a bit and his head was shrunken. And on the subject of the MC, if he's going to be involved in any future sexual content, you gotta fix the guy's peen. Lol. It's almost literally a pencil
If the dev is reading this, I don't mean to be an ass and I hate giving critical reviews. You obviously have enough of fan base that enjoys what you put out and that's more power to you - but this just wasn't it for me. Good luck in your future updates
