I have decided that once I finish testing out some more mechanics for skills activated in the field (for puzzles and encountering enemies, etc.), I will continue map and scene creation to progress the game's main quest.
However, this means I will have to add more character dialogue, something that is not exactly a priority for me whereas gameplay most certainly is. Therefore, I will begin adding placeholder dialogue reminiscent of original Zelda NPC dialogue and other NES titles (but with less translation errors!) just so you know what to do and where to go, stuff like that, despite not deliberately going for that sort of minimalist/nostalgic style regarding the dialogue. I hope this will be a good strategy for me to stay focused on the gameplay and to elaborate the dialogue and personalities later on.
