I'm glad you like the designs. I understand page selecting can feel a bit odd at first but it's basically a wheel inventory with 4 directions and makes things a lot faster after playing a bit. Using spell cast button to change does sound interesting tho so I will try and see how it'd work.
World design and maps aren't final but I see what you mean since you can maneuver better and start more equipped than link, except for the few last things that aren't done yet mechanics are kinda recently finalized that I can actually tackle world and screen design more in tune with the movement speed attack directions and whatnot.
I recently put the text box stuff together so some npcs don't even have those but the ones who do if they're moving around in scripted event they're talking on timer, game doesn't pause after each line for you to press a button to continue because of that. And the npcs that stay still show the text once you're close enough.
Flying bits are definitely not final, they're basically spectacle like you said, planning to scatter them around to break the regular gameplay and I'm planning to add a few more. Dragon controls slippery on purpose since there's going to be a strong wind visual effect to indicate you're flying with resistance and you're gonna have to avoid more stuff.
Thanks for playing it and leaving feedback, I really appreciate it, definitely will try the x/k for spell changing.
