Jouette:If you played day 1 and day 2 already:

- You can use your saves. Your autosave and save slots will probably carry over, but 100% compatibility is not guaranteed unless your save slot is at the end of day 1 or day 2. If you find your save is somehow broken in the new version, you can finish playing day 2 at https://jouette.neocities.org/fivedays/archive/day2/ and then load your save from the end of day 2 in the main game.

- You can do a custom start. Choose "New game (from day 3)", then "Custom start" and select the options you did in day 1 and day 2. For even more customization, you can click edit gamestate at the bottom to select minor choices as well.

If you need to use incognito mode:

- It's completely fair that you wouldn't want others in your household to know you're reading erotic stories, especially if you share a computer.

- However, it also means that you won't be able to make use of the save/load system to keep your progress because your browser will delete your save slots when you close it.

- As a (bad) workaround, when you want to pause the game, click edit gamestate and remember (or write down) your friendship points and choices made. Then, to resume your game later, you can choose Start from scene... in the main menu, choose your scene, then click edit gamestate and put your values in. That's unfortunately the best I can offer in your situation.
