Okay, this is just assuming that this works the exact same as Wordle (Which it does).
The scenario of you guessing, for instance, "E" as the last letter and it being green, and then guessing "E" in the second to last place and it being yellow in TWO SEPARATE TURNS (Like "E" was ONLY in the last place and green in the first turn and was ONLY in the 4th place and yellow in the second) doesn't translate to there being two of the same letter.
