I would love to see this idea in the game! It gives a sense of interactivity with the environment around you, which I like. It would create a sense of nostalgia too. It could even be used occasionally as a puzzle or a way to defeat enemies.
Though I don't like the fact of burning a whole forest down for rupees. Maybe I'm a treehugger of sorts, too.
I would love it if that would happen, but in great detail like you see the tree burn down all detailed and stuff. and you could burn OTHER things in detail, like a fence or a monster
I think that being able to burn trees or bushes would be easier than having to swing your arm around trying to cut it all, just to find hearts and other things. It's be a time-saver and you definitely wouldn't have to tire your arm out.
