Lovely opening sequence and the flow after that still remained as fun and interesting as well :)

Stellar. For some reason or another I wasn't able to get through the first version, but this one it's much easier to see the idea :) Thanks!

Really cool setting. Just took me a short time to figure out where the initial 7,8 and 9s went, then I was off.

Very smooth, also think it's a 2 star puzzle.
