Very ambitious and cool! Great to see an indie hack-and-slash in the likes of Diablo and Path of Exile revolving around pirates. I think the rum bottle is a cool innovation on the potion system. I think it has a solid core that just needs some polish and tweaks to make it more pleasant of an experience. As it stands right now, I think the game should default to showing health bars above enemies since without them, the game doesn't provide enough damage feedback to show how you're doing in a fight. I think you should also always have access to your sword melee: don't bother with the rifle melee as it is worse and if you don't have pistol or bomb ammo, you get stuck with the rifle melee with no way to bring out your sword, which I think is silly. The fiddle should probably also only drain rum if you are actually healing teammates: otherwise, it'd be nice to attract items without wasting rum. Leveling up should probably pause the game as well when you pick a perk.
