This was sorta kool but it does get boring so 3/7 :) good job
Very Nice! Keep it up!
Everything is Cool and well made, music needs a bit of work, but that doesn't matter a lot, my rating is...9!
This is a great puzzle some are easy and some I'll have to take time to figure out, its really a cool concept, and I love this sort of "piping" game, it reminds me of Mad's spy vs. spy boardgame that I used to play back when I was a kid. You have a lot of cool puzzles here and I definitely think you should pursue making a sequel for this one.
