Very nice puzzle, thanks for sharing. I had my "oops" at the end, I didn't read the rules too carefully and for some reason thought that the "11" clue was a little killer clue and ended up with totally different end result :)

Thanks for the Colorado series!! Such a great introduction to coloring :) I solved it in roughly reverse chronological order, which means that this is the last of the Colorado puzzles I've solved. (Maybe I should've started with the first instead of struggling through 7 for a week, haha.)

Fantastic puzzle!! I greatly enjoyed using colouring and alphabets to denote the numbers. The final disambiguation was wonderful. Thanks Florian!
