Man, I hate looking along diagonals - but your puzzle is always so damn interesting and hard to resist.
BTW, I copy the puzzles onto paper and draw the diagonals as dotted lines to help me visualize. I also duplicate the clues at the opposite end, and note the length of each diagonal (e. g. 2/5 instead of just 2).
Update: With the little help mentioned above, this puzzle turned out to be Easy (2 stars) - but Very Nice nonetheless.
