Not a bad start for a concent demo, it can go anywhere from here.
It gets flagged by Windows Defender for a trojan, which is a bit spooky.
The game seems a bit linear, I like it that there are choices, but each all of them lead to exactly the same place. It's fine for a demo like this, but it's something to consider for later on.
The art style is great, but I think it would be better to introduce changes to make it uniquely yours. Otherwise, people will just talk about it as "it's like Summertime Saga, but..."
The voice over is a good idea but not letting us change the text speed can make the game boring for faster readers. I know that we can just click to make the text appear, but why not allow it if it's already in renpy. If you think that the story will change over time maybe it's not worth it to pay for voice over at first, as you'd throw some lines away anyway, or have unvoiced lines mixed with voiced ones.
I like how interactive it is, having to manually turn on the shower or make the coffee by clicking on the coffee machine. It would be great if you'd use this mechanic to reward the players for paying attention to details. Like the game doesn't prevent you from making the coffee without milk, but it rewards you with a kiss on the cheeks and a closer sneak peak into her cleavage if you don't forget it.
Keep up the good work, I might even consider subscribing to your patreon in a few updates.
