Oceanhorn will live and die on people's assumption that it somehow emulates a sort of Wind Waker experience. There's been very little evidence of it thus far though apart from it looking like it, along with a character walking on small islands, riding a boat and placing bombs/button mashing simple enemies.
Show me something akin to an expansive Zelda dungeon and it has my attention.
It's understandable, though they seem so focused on recreating Zelda experience, down to the battles and exploration... who knows maybe it will be a good copy? But it's true, the game will get slagging for what it's NOT rather than what it is, regardless.
I am cautiously optimistic - I am really curious about the fact Nobuo Uematsu and Kenji Ito are collaborating on the score - how legends like that got to work on some iOS game? Maybe it's silly to get the big ideas, but it might be a nice Zelda-esque game.
