I think this game is promising, and i look forward to future iterations of this game, however I see some flaws that are holding it back right now.
First and foremost, having to physically move around the house to do chores like showering and eating doesn't really add anything to the game, in fact it makes it significantly slower and clunkier, especially with the slow movement speed. Keeping up with stats like cleanliness can already be annoying in a ren'py came where it might take a couple clicks to clean up, but having to wait as the character slowly ambles about the house quickly gets tiresome.
The second point is more speculation, but i think making a game this "custom" will make the game WAY more janky, buggy and slow to develop for. For example, my playthrough ended after 20 minutes or so when i clicked the stairs while sitting on the toilet, causing my character to float down the stairs, then become locked in a walking animation forever. I'm not saying you shouldn't custom program all this stuff, but prepare for thousands of similar little issues like this to pop up.
I don't want to come off as too critical, i think this game could become really good, but at the moment i'm a bit concerned that the 3D movement aspect of the game could have more negatives than positives. However, that's ultimately just my opinion and i hope to be proven wrong about that in future releases!
