Also since I've seen many people asking for a walk-through in this thread i don't know if i can link a guide so ill start with some basics, I've cleared the game with no cheat engine usage.
Always shoot a play minimum 40 secs for the long video bonus badge. vid length translates to more income and you can always edit down clips to 20 secs if you need to in the future. max vid length increases as you progress the game. You can reuse a clip after 5 other vids have been sold. raising the heroines intimacy/lewdness unlocks more scenes which = more money.
Only do dates if you have nothing else to do. Text the heroines everyday bc you get a stam upgrade when you finish all text conversations.
buy the upgraded camera ASAP because it will make your shooting more efficient. the max difficulty on mini games is a pain in the ass but they permanently increase your max stam which makes the game much easier.
Gifts are OP, buy them and use them ASAP because it will raise the heroines stats and they are one time buy/use.
I recommend missing the debt deadline twice at the beginning of the game and just spend those two weeks shooting. then third week make vids and sell one once a day everyday of the third week and you will have a very comfortable amount of money.
The perfect day one is too unlock the internet cafe, pool and park, collect all the h tokens, beat inferno on all the mini games, give the h tokens to man in park and you will end the day with plus 15 max stam. If you have any specific questions ill try to answer them.
