You made a grave mistake: the short cutscenes that happen when i activate a switch in a level.
They are not good for this game. Their purpose is to show me what it is that i've activated but in this game, i go very fast so these interruptions are frequent and i cannot play for 5minutes without my speed being broken, the whiplash of this stop-and-go feels terrible.
I should be able to speed past the various switches and activate them without stopping. Only the important water droplets should retain their cutscenes.
If this cannot be done because they are meant to hide some loading in the level then it would have been crucial to make it so that they don't.
In Journey this puzzle-like convention did not pose a problem because the pace of the game was much slower. I don't think Abzu even had any of those. The Pathless was a puzzle heavy game so they made sense. In Sword of the Sea they hurt the game.
This is the only truly large flaw i want to complain about but on a first playthrough it will not be a problem, a player won't care. Being able to skip cutscenes would be an easy solution but adding a toggle in the options so that they don't play at all in new game plus would be a very elegant solution.
