It should start with easy words and increase the difficulty later. A big part of the success of Wordle was a very curated list of words to guess.
(Does it show difficult words after I make a mistake?)
If I'm typing a word and I miss a key and then press two before I realize the mistake, then it counts as two negative points. Perhaps the program can stop giving negative points until the user press a correct letter.
The typo is rather brutal, at least since i usually make several typos at once :D
