Hello Mark - thank you for asking! I have in fact proceeded, and am now on Path of the Shell trying desperately to swim to the tower, without much success! What are you playing now or does lawn cutting take precedence?
I'm about 75% through "DEAD REEFS", which is an interesting and pretty game. I hope to finish it rather soon so I can write a review of it. The only problem is that there is so much good, and so much irritating, that the review might wind up about the length of MOBY DICK. Ah well, Mr. Bill is welcome to edit. Enjoy "The Path..." It has it own unique set of frustrations, but like everything URU, it's worth the trouble
As for the grass; it's August and I don't water. The lovely green has been replaced by ugly, but no maintenance, brown. I like it a lot.
To the best of my knowledge there are no patches for this game. Even worse news for you is that I just finished it and had no operational difficuties at all. Whatever else it is, it ran pretty smoothly.
