Current bugs/issues I've found, as of v1.04:
-only happened once, but the very first time I used the meals menu, the "scrolling" for lack of a better word was EXTREMELY fast, making it near impossible to select the thing I actually wanted to make. Only happened on the first page, and fixed itself when navigating to the intermediate page and then back, never happened again, but hey, it is technically something of note.
-this pretty much won't happen if you're not a complete moron, but I absolutely am, so if you start a run of the turquoise coast and immediately use Sami to swim over to the small island that usually has a chest without first dealing with the crab enemy that spawns right by the starting area, then that crab will hit you upon attempting to swim back to shore, knocking you back into the water and rendering you unable to move, forcing you to reload to your last save. Again, will not happen if you're not a dipshit, but it's a softlock so I thought I'd bring it up.
-Pretty sure the combat tutorial said that you're supposed to use Q/E to swap between a character's selected ability, but uh... I couldn't get it to work. Ever. I also tried using 1/2 just in case and that didn't work either, so I don't really know how you're supposed to swap. Might just be an idiot as previously established, but if anyone can tell me if I'm doing something wrong, it'd be appreciated. EDIT: welp, can't rightly recall what buttons the tutorial said to press, but A/D work just fine. Again, I may be stupid.
-Like the guy below me said, upon finding the hidden scene in turquoise coast, the art from that scene can stay stuck on the screen. This unfortunately will persist when traveling to new areas, and sticks around even after closing the game if you saved after it happens. Not sure how to undo it yet aside from simply loading a save from before you find the scene. Edit: you can fix it by running into town, going into Gigi's lair, into the side room you unlock after doing Luci's side quest, and looking at the mysterious book. If, by chance, you haven't done that quest before encountering this issue, however... you may be outta luck. Seems like if you just put a different instance of art up, it'll override the old one. It's just kinda hard to navigate to the new trigger with the old one blocking most of your view.
-This one might be a feature and not a bug but I have no idea. Characters leveling up does work, but the vast majority of enemies don't give any experience. It seems like only the ones with ranged attacks give xp, which makes progress very, very slow. As in, double-digit expedition counts just to get characters to level 2, let alone anything beyond that. It's not crazy important, but I do like the combat, it just feels like the amount of time to get a single level is a bit much. If it is an intentional feature, maybe consider allowing more enemies to give xp, but restrict it so only the currently active character gets the credit instead of both members of the party? I dunno if that's even possible, honestly.
