Great stuff, looking forward to the next update whenever it's done cooking. Gameplay, story, and characters are all super fun.
Minor issues I found:
-when using Sami's swim ability, if you immediately try to go back where you just were, you can often end up walking straight off the dock instead of swimming back properly. Not exactly game-breaking, but still something of note.
-as another commenter mentioned, scenes with lots of pictures can slow the game way, WAY down. The side-mission stealth section had a bit of that, but where I really saw it was in the mainline quest during Luci's cannon-loading minigame (Luci really can't catch a break from the lag, huh?) presumably due to the arrows for that minigame being considered entities in need of loading... or something, I'm not a game dev. Either way, that scene was supposed to be a tight timer, and it progressed at an absolute crawl.
-during dinnertime, sometimes you'll be kicked from the table long before your patron is full, having to re-initiate dialogue to continue the feeding, and sometimes you won't be kicked even after they've surpassed their cap and thus shouldn't be able to feed them any more. Hasn't happened to me yet with Mina, happened pretty often with Luci, and haven't tested enough to see if it happens with Sami. Notably I recall being on the beach every time it happened with Luci.
