Colorful and creative. I like how this is a continuation of the last series, and there seems to be a running story line, if the aliens are telling the truth. I also liked how we get to see some of the alien civilization and not just another instance of being marooned alone.
I didn't like the puzzle. Even though I understood the clue, I still had trouble putting it to work. Not sure why, but it looks like a lot of people have struggled with it.
Tempted to go onto EG24 to finished the series now (the whole thing is up there), but I'll try to wait so I have something to look forward to every day!
