This game could improve and get at least a 4, with the correction of some significant flaws.
1. The artwork is inconsistent and it doesn't look like much effort was put into it. We're all pretty familiar with the backwards spelling issues from mirroring characters but it looks like different artists drew the usual characters versus the sex scenes and animations. Suddenly the girls get much larger and are barely recognizable from their usual selves. And some of the ahegao faces actually look much more like the character is trying to keep from sneezing.
2. Ah yes, sex scenes. With few exceptions they are all "Faster/Faster/Cum". there's no point in slower or keep going other than to see the text again, which might be necessary since scroll-back is disabled. If the developer wanted to do something different, require the players to go through some extra steps in response to the character responses to get to the climax ("Oh, baby, let me catch my breath" --> click Slower) but as is they're pretty much standard repeated dialogue and just get through the three button clicks.
3. Bad grammar. It looks like this game was originally done in Spanish and then ported to poor English. Please someone, teach these text porters how to say "I am thinking about going" rather than "I am thinking to go".
4. Typos and inconsistencies. Character name changes/typos go unchecked even after numerous updates.
5. Missing images. But at least it handles the missing images instead of doing a screen dump.
6. Poor pacing/Difficult sandboxing. Although the game is supposed to be a sandbox game, many of the events are: Brixxia wants you to take care of Mia first. Mia wants you to take care of Linnet first. Ruby wants you to take care of Linnet, Olivia wants you to take care of Linnet. OK, so it's really a linear game here where we need to do Linnet before we can do much else.
7. Bad event triggering. Some tasks, like "See Mia at school in the morning" don't fire when you go to school in the morning, but will fire a day or two later.
8. Conflicting tasks. Although there are, technically, 3 periods in each day, most of the events need to happen in the afternoon, and several of the morning events take all day. Afternoon events can be ask simple as communicating a task is finished and being told there will be another one tomorrow --- and suddenly it's night. Which means you will probably only get one event per day. It seems as if the developer thinks he's getting paid by how many day's you go through. Thankfully time is meaningless since two characters will both tell you you need to do something for them "tomorrow" at the same time, but you can even do it 3 weeks later.
9. Overly grindy. The initial minigame or collecting magic is fine but having to clean the church N times, study with Mike N times, decorate the church 2N times, fix the shower 2N times, deliver or screw up deliveries 2N times, without appreciably advancing the story, supports the theory that the developer thinks he's paid by making your character sleep between events.
10. Non-responsive/Laggy timed minigames. I don't have this problem with other Ren'py games but this one does not respond quickly when clicking tiles and images, meanwhile the timer is running down. Sometimes if you click twice, the image will select and then unselect. The developer should put in a SKIP button for most of these minigames.
11. The game is presented as "Living with two adoptive mothers and stepsister" but there is not an actual no-incest option. It's all incest.
12. And some of the characters (e.g. Mrs. Jones) would only be appealing to a very small segment of society but you can't skip them.
On the other hand, the story could be reasonably fun and amusing. The plot aside from the tropes is not overused and can be interesting.
