Cheers, I don't think I will have the capacity to support updating two courses in addition to working on my own games, so I'm going to say it's unlikely you would see a Top-down Adventure Game course from me.
That being said, although the examples shown in LBaP! are to service the creation of a platformer, many of the concepts learned in LBaP! are directly translatable to coding something like Zelda. Specifically things like creating a HUD, in-game shops, cutscenes, obstacle and enemy behaviors, UI design, SFX and Music management - all the lessons in LBaP! provide a foundation for creating any game in GB Studio.
