I am now about three-quarters of the way through Myst V: End of Ages. As I suspected when I was half done, the remaining parts are the ones that are harder for me. I made almost no progress in the last week and a half, until tonight when I noticed a detail I hadn’t noticed before—and I’ve been spending the last week looking for such details—and was able to finally complete correctly the part of the game that I had previously solved accidentally.
Unfortunately, the part of the game that remains is not only probably the most difficult (since I’ve left it for last), but also seems to be the most taxing on my computer; the interface is getting very sluggish and slow to respond, which makes the gameplay much less enjoyable.
On the positive side, I haven’t opened the strategy guide. Yet.
