I greatly appreciate your kind words and taking the time for such an extensive bug and suggestion list! It is the best way for me to improve upon the game.
Looking back, I think you are right about making Yua a party member vs Nixie. The original idea was I liked the romance hints from the original game between Nimfu and Jean; however, the relationship was so toxic I wanted to do something a bit different. This is a change I definitely will be looking at next patch.
I am glad you enjoyed the party banter; I am hoping to add more dialogue between characters. I will also look into fixing the issue where moving from map to map cancels the dialogue. I did shorten some quest lines and streamline dungeons for a more fun experience without going through mazes and encounters every 3 steps.
There should be 3 carpenters and you get to choose 1 for your style of town. Once chosen, the other two should be unavailable. The walking on walls and invisible walls is where a lot of my time is spent trying to squash them. This one is on me as I should have organized my tilesets more efficiently.

The Great Bird Quest has two solutions. The first is you refuse Mina to join you and you don't have enough love from Nina for her to join. Mina will then steal the seal at night time (cut-scene) and turn to the great bird. If you let Mina join you go into the dungeon and Nina gains the power to transform at will. Use the Shift Key to call the bird and move down 1 square and hit enter to board it. While Rand ball and Jean frog works great, the Great Bird has been giving me grief to get it to work 100%. I will look at the Mina tower triggering when it isn't supposed to.

If you are getting the Ryu.img error, go into your game folder and delete the auto-save slot (Slot 1). This is a weird error been getting reported and keeps popping up randomly and appears to be linked to the dragon transformation and dying.
I will work on a guide/walkthrough for the next patch for sure because there are quite a bit of changes and things happening not clearly explained in the game.
Regarding the encounter rate I think turning off random encounters is a more modern approach, but I left it in in case people wanted the OG experience of walking and battling. I need to look at some of the level tweaking and experience gains. Also on this patch all gems and crystals do flat amount boost vs % boost. I do believe I left the Shamans unchanged, so I will need to look into that. Honestly the balancing of the game is where I need to focus more on as I didn't have any testers this patch to try all the different builds out.
Regarding skill trees, I wanted to get feedback if people enjoyed it and wanted to see it expanded to other characters. I might have gone overboard with the customization, but I really tried to make every character viable so it was the person's choice to play the characters they wanted. Nixie's curse ability prevents healing on monsters. Basically it creates a bubble (around 3,000 HP). When an enemy is healed it instead applied to the bubble instead of their health bar. Once the bubble hits 0 it breaks and they can be healed again.
Again, I greatly appreciate all your feedback and bug reports!
