I liked that. Way too much echo. I had trouble understanding the words. As I said, I found the puzzles pretty easy. I got stuck in exactly three places, each time because I'd missed spotting an object or exit in the copious scenery.
Unobtrusive objects are fine, but the sense of focus was too weak at times.
I must say more about unobtrusive objects. In a very broad game like ROTS , a game with many parallel routes to explore, you usually get stuck because you missed seeing something. And re-exploring the entire game is painful . As much as I love a really huge environment, there are obvious disadvantages when you realized you missed an object somewhere . And that's the other reason I don't mind cheating to find out where it was.
