I had the benefit of having the Itch launcher open on my other screen so I was able to finish it in about 10 minutes. Very cool little game!

Clever way to show the numbers. I managed to complete the puzzle.

Maybe a way to mark cells you are certain are empty would help at harder levels. And a key to open colour-number help would be nice, as you said.

This looks like a good game, and I love nonograms, but I'm afraid it was a little too hard to keep track of the colors and their values. Maybe put a screenshot of the help menu on the game's page would be helpful?

Also, I didn't really get what the checkerboard colors were.

Using colour was a really clever way of overcoming the resolution limitation! Unfortunately it comes with its own challenge: I had to pull up a second window of the game to refer to the colours on the help sheet constantly. Still, nice job on implementing a tiny nonogram. With some determination I did manage to make one (1) smiley boy.
