But if you must.....
Save the Date starts out as a dating sim, interactive novel kind of thing and then quickly sidesteps into a commentary on gaming and the techniques that have become a normal part of game design. It's mostly static backdrops with lots of conversation, as such I spend most of this video reading dialogue from the Female love interest.
If you've played it to death, seen a dozen different endings but still can't figure out how to get the happy ending, then skip to the 58:00 mark to see how to think outside the box and make all her dreams come true.
I haven't exhausted all the dialogue options, but I think I've covered all the game over scenarios.
