Interesting one, thanks. I worked out the rules surprisingly quickly, solving the puzzle took a bit longer...

great ruleset and a very enjoyable puzzle. after having a bit of trouble figuring out the ruleset, the puzzle itself not being too hard was a welcome surprise:) thanks for setting!

This is the kind of puzzle that lets you feel you've made actual progress at solving. I first took a look at this a dew months back, and I quickly skipped because I did not know what the hell I was looking at. Taking another look today, it only took me a few seconds to understand the ruleset. Ok, maybe I'm a bit biased for this one... Anyway, rivers of fun this time around ! Thanks :)

Awesome. The actual puzzle was just as fun as figuring out the rules.

The solve was smooth and had some interesting deductions! I liked this creative ruleset, even though understanding the rules took me longer than solving the puzzle.
EDIT @Mark Sweep: thank you, Mark! I actually hesitated to the last moment whether to post this puzzle as an Instructionless or whether to give the rules, and post is as a normal puzzle. I knew that I would get many more solves if I gave the rules. But in the end I decided it would be more interesting with the additional challenge.

Really interesting and enjoyable! Figuring out the rules is the hardest part, due to which I'd give the puzzle 4 stars difficulty, but after that the solve is more like 3 stars. Thanks Jesper!
