While I still very much enjoy the things this game does that you simply don't find in other games, the things that are very uniquely Fumito Ueda, it is a bit frustrating how sometimes you're pretty certain you know how and where to continue, but it doesn't work - and you don't know whether that is because Trico isn't following your commands correctly, you're in the wrong place, or you're barking up the wrong tree entirely. After the first encounter with the
spoiler:, I found myself in a corridor with one large window being the only obvious way to continue - yet it took me about ten minutes to get Trico to go there, including several trips back to the other rooms, just in case I had missed something. In the end, it turned out that my first idea was the right one, but Trico was having a very long stubborn moment.
