I just copy/paste the url for a kind of "save/load" function. As for points lost, I do the same kind of reloading, to get the points back.As much as I like these types of games the inability to save progress before making choices really ruins my enjoyment. Sometimes the outcomes for certain choices are so unpredictable and unfair it's disheartening, and other times the hoops you have to jump through are so obscure it's amazing anyone ever finds the solution. Without a proper walkthrough for them (and I think there's not even a walkthrough for these on vdategames) you're usually better off just downloading it and looking at the image folder.
You're right, it can be pretty disheartening, and just genuinely not worth wasting so much time just to get to that same point and pick the right choice.
