That was a lot of fun - a few moments staring and wondering how on earth I could move forward, but the next step of the flow was always there.
MSDOS: glad you liked it, thanks for the comment!

Very, very clever. I was very pleased to get the initial logic, and the puzzle guides you through the rest. How people set puzzles like this is beyond me. Thank you so much for the challenge and entertainment.
MSDOS: Very happy this was an entertaining challenge! Thanks so much for the comment!

Very clever setting. 2.5 starish for me. Great fun thx.
MSDOS: Thanks wuc! I do think there are a couple of steps that are maybe 2.5 logic as well.
