Galleon's Graveyard at best, is well, fun, but a bit broken. In the whirlpool parkour, sometimes the whirlpool at the bottom will cast pull and basically make you spiraling down the entire parkour, forcing you to do it again. You could fix this by not making them mobs, but instead you having to stand on them to levitate, kind of like the particle parkour in Headless History. The next part is the boss room. Although I have no problem with the gimmick, the thing that ruins it is the fact that Redbeard has pull spell and wave spell, pushing you off the pressure plates, making summoning the cannonballs a pain. Basically, remove these spells, and replace them with multihit. Yes, multihit is basically push with damage, but at least Redbeard isn't going to be yeeting you off your plate from across the room. Another problem is the fact that during the parts with the enchanted cannonballs, sometimes the cannonballs just target the minions and not the thing your supposed to kill, wasting cannonballs. So instead (idk if this is possible or not), give the bosses priority target, so the cannonballs go for them first.
