Pretty fun. It would be nice if it colored the pixels on the keyboard letters to match your known hints (e.g. when my guess was F but the letter is P, then when I am on the appropriate column, the T in the keyboard should have 4 green and 1 red pixels on its top row).

In the instructions I think there is an error. It highlights ‘F’ halfway green and in next step it turns out that letter should be ‘E’. Isn’t F subset of E except for missing bottom horizontal piece? Why isn’t the whole F highlighted as green.

First guess only shows the top line match. Second guess shows the two top lines match. And so it goes.

ah makes sense now

interesting concept… I skipped the wordy instructions and found it intuitive. really nicely done, lovely UI (apart from the enter key on the left).

The "Enter" may not work everywhere...

I think "FIRES" gives you the best toprow hint

"TITER" for one more pixel.

I feel FIFTY gives a bit more info. I like having all the top corners

FEEZE gives a full top row.

Wow, after using this word I got 6 in a row of pack 1 in exactly 2 guesses.

Using it gave me this
