-It's very unclear what exactly happened to the MC in the beginning. I assume he and his parents were in a car accident, and he was the only survivor. Which would imply he then moved to live with his aunt or a friend of one of his parents, or was placed in some random fosterhome. But, it isn't specified anywhere, so it's all just an assumption. Might as well have been his father and his stepmother who died in the car crash, making him move in with his real mother and his step sisters. Relations and past are really vague.
-Animations aren't skippable. I know developers spend a lot of time and effort making these, and they do look pretty nice, but for me personally, they last too long. Especially when nothing else is going on, like, some conversation. It varies for everyone, I generally get the gist of what's happening within 3 seconds, so would like to have the option to click it away instead of getting stuck on an animation.
-It's translated, but I wouldn't call it Engrish. There's just occasionally a wrong word (like, his tattoo is on his arm, not on his hand), but what I saw more often were typos of the light-dyslexic variety: letters being switched within words or on a rare occasion with the next word. A proofreader should help sort those out. A spell checker might help too, but I think a proofreader would be better, and circumvent the problems that come with spelling checkers. Without those typos, the writing is actually quite decent.
-I'm never a big fan of having both dom and sub paths without anything inbetween (not to mention, I'm actually not into BDSM at all), since these extremities make no sense without a middleground, but we'll see where things go.
-When you release the next chapter/version/whateveryoucallit, write a short synopsis of this version, and use that as game description. So, something like:
That still doesn't say much about the story, but it already helps people more to figure out whether it might interest them, or help remind them when you release v0.2 and they almost forgot what v0.1 was about.
