I think I know how the game is supposed to work: it's just chatting up the girls, then doing a few puzzles which are all pretty easy. Just a picture sliding puzzle, then whatever is meant to be going on with the lock (Just click and hold to keep it in the blue zone???), and then a basic card memory game. But there's a lot of stuff I'm confused on.
When you click on Daemon's screen, there's a little arrow minigame you can do that I think gives you money? It crashed on me twice so be careful, I guess.
Absolutely no idea how talking with Daemon works. It just repeats the same few lines of dialogue based on how your progression with the girls is. At one point it says it wants to give you something, but it didn't give me anything.
Other than nightly buffs, I don't know if there's a way to lower the virus bar. You can pause it for 1 day with an item from the shop, but that's all. On the same topic, the heart from the shop doesn't do anything afaik.
There are supposed to be random days where the girls will be out of their house, but occasionally it will still show them in their house. This is just a visual glitch, and they're not really there.
I can't do anything with the clerk girl who asks you to sweep. Not sure if its a bug or she's just not implemented yet. Whenever the two girls are out, I just play the arrow minigame or pass time.
Also whenever it prompts you to pick a buff and debuff at night, DO NOT pick the debuff that randomly chooses for you, that shit completely screwed me over. It's not one night, it's permanent for the rest of the game.

Consider this an early guide, I guess? Just talk to the girls to progress. Solve the puzzles, which are all really easy. If I can do them all first try, you definitely can. Keep an eye on your virus bar and try to pop those antivirus items from the store once per day to slow it down. If the girls are out, play the arrow minigame to get more money and buy more antivirus items.
