I finished the game and have a few questions, a few mysteries I couldn't solve:
1. How to make friends with the guardians in the cave inside Morito village? I assume one needs three of the key-shaped hole item, and combine them. I've got the three counts of the item, but how and where to combine them? (I found the answer: to combine the key, you use the pots inside stores)
2. How to get inside the bathouse in Pixel Castle? I remember there being items, it must be accessible.
3. After beating the game, how to get the Yggdrasil cane? I suppose it must be crafted by combining the rare items you get from befriending strong characters, but how and where to craft them? (this does not seem possible using the pot mixing in stores like for 1.)
4. There is a door locked under the creepy area's "rock bar", the last zone you explore in the story. A big church-like room, with this big locked door with nothing but darkness visible through the bars, and stairs on the right to continue the story like normal. Is there a way to open this door?
5. Is there a way to free the frozen/crystalized figure deep under the water cave, where you get the old magic book that translates the old language? I suppose the answer is no because it wouldn't make sense given the gallery room (in v.1.4.10 at least).
