Bugs:
Despite the game claiming I get a recipe for Blubberfin oil(I think that is what it was called?), or something like that, I have not been able to find it anywhere to craft, neither in campfires, or the crafting stations in my house, in the current 0.1.3, yet I remember crafting it in the previous version
Portraits for people in the encylopedia, usually doesn't show up the first time on a day, you check them entry in there. (You probably need to ensure they are pre-loaded, there are plugins that can help with that, at least for RPGM MV)
Using a Charming Bait item, doesn't seem to use up one of the baits, and also doesn't add any buff icon to the player, BUT it will remove the buff from Magnetic bait. Which magnetic Bait despite it's description doesn't seem to go away when you sleep
The FC-5000 fishing rod, claiming to give one strenght, seems to actually give 2 (at least 3 barriers are broken per click with it as the only strenght item equipped)
When Kaz is at least at the highest weight stage (when you can craft "Ring of the Waters"), if you go into her shop, she seems to sell the 3 old stat rings, including one of them giving "Speed", and buying any of them, they will not qualify for the upgrading recipes.
QOL Suggestions:
Make it possible to craft multiple of a recipe in one go.
Likewise make it possible to open multiple chests at once, they can stack up in pretty high numbers towards the end of the demo.
Also it is unclear, if there are any point to the normal attack, defence, magic attack etc. stats? And if not, wouldn't it make sense to use those(renamed ofc) instead of some hidden variables or whatever you use for the Strenght/Bite/Reeling/Luck stats? Would also make it easier to see at a glance, how much you have of each, specially when you have multiple sources. And yeah at least regardless, it would be nice to have somewhere to see the total of your current fishing stats
Also seems like there is nothing fitting into the head Equipment slot?
Despite all that, great game, can't wait to see where you are gonna take it, in the future. The upgrade to the fishing system in 0.1.3 was HUGE, far more intuitive, than the old version, and easy to actually see what you are missing to be able to catch fish, you can't at the current state
