@eSheep That was the literal opposite of my own reaction. I thought they had balanced recent and old Zelda games wonderfully. I may be wrong, though, because I can see how a lot of puzzles could be solved by using the same object/principle time and time again (i.e., a bed, or a pile of beds, to climb over obstacles).
If you can summon the bed from the starting area anywhere anytime without restriction I think it will greatly affect balancing, because why bother using anything but the dominant strategy?
But if it's more limited, say for instance you only have a set number or times you can summon an Echo before having to find another source to scan, then it might be more balanced?
Because from what they've shown so far, it feels like as soon as you get a flying bird or a wall climbing spider, walls would just be deleted in practice.
