You can transfer your save files, yes. Just make sure you make a copy of your save folder before you delete the old version of the game, because RPGMaker saves its games within the game folder itself. Also, copypaste the entire save folder, not just the separate files within. As for the content, I can't say for sure how many hours that'd be, I'd say it depends on how much of a completionist you are. The Patreon build has the full Deep Mines dungeon, which by itself can take a while if you're gonna collect everything there is. The Quest Guild also gets a booth on Paradino in the Patreon version, with new items, and 9 new repeatable quests if you have the gold badge, and "reward". Some of those new quests also got way more to them than just "Go fetch thing" or "slay enemy". You can also finally enter your Guild Home, which has some new additions as well, including a buff system for your chars, depending on their levels. There are some new lewd events the public build doesn't have yet, of course. Six regular ones, and a new pixel-animated one. The main story doesn't go much further beyond the chars talking and spending one night at the hotel. Paradino in its entirety is done at this point, and after you're done exploring the hotel, you can check out the first draft of the next island. There's not much there yet tho, just a bit to explore (and one secret).
