Critical problem
What little I was able to play of the game looked promising. Good concept. But, I tried to save the game early on, and immediately ran into a problem.
The "Save Game" function, besides being slow, caused Safari version 3.0.4 on a Mac running OS 10.5.2 to run extremely slowly. I had to abort the script. I don't know if this is peculiar to me, but I regard this as a critical problem because it makes it unplayable. It needs to be fixed.
I'm not actually going to vote on the 0-to-5 scale, yet, because I'm assuming the author will make an attempt to fix the save/load problem. If the author does fix this, then I might vote to give it a good score.
