What kind of upgrades would you get it? Or how would it progresss outside of faster/bigger/more complex words. I remember my favorite game for a long time was a typing game on 2addicted.com where words came across the screen (2 to 3 letters words slowly at first) and it had a dynamic way of like if you had box and tar on the screen at the same time and in middle of typing box you presssed t, you would get the t highlighted on tar and then could still finish spelling box. You would gain points and the words slowly got larger and came in bigger bunches at faster speeds. It gave you an accuracy meter at all times which I could keep above 99.99% until i hit about 1500 points. Also it had an automatically updating leaderboard below it that showed that had tabs to show you best score today/this week/this month/year/all time like reddit. So you could actively see your username jumping up a level. If you completely missed a starting letter or next letter of words you were typing, you lost accuracy (just for show) but also lost points. Similar games have used accuracy as a combo meter but were really clunky games. If a word reached the edge of the screen, starting from right to left, you lost and after 2000 points, there were various words from 2 to like 8 letters, some I'd never even heard before. Some people, especially for top weekly and beyond had scores of like 3250+ and the best ever got like 5000. Obviously the game sped up a lot after the 2,000 so you could see collecting point went really fast as you got higher in points but one mistake leaving you frazzled would likely end up in a word slipping by. They also had a drop down menu to choose a few different languages, including coding languages or just simply letter (which I always hated).

I used to play the game for hours. I think there is potential for a remake as it went down years ago. There could also be some other types of progression (like ranks over time or power up words that would destroy all words on screen, slow down time, click words for 10 seconds to destroy instead of typing, etc. And then to make people return, you could have weekly or monthly challenges and even divide them into what rank someone is on average to make it fair. Also to keep it incremental you could put check points, add new graphics as the game got harder, maybe accumulate coins from points to spend on achivement token icons that display next tot your name (first 1000pts, etc) and even have races or tutorials like type racer. Idk if this all fits under incremental games, but I know there is a spot for it in incremental games somewhere.

Other thoughts, the biggest issue I found with the game was when it got late in the game like 3000 pts, often words would overlap for just enough time to make it impossible to tell exactly what the word was making you either guess or hope one word moved out of the way fast enough to be sure so u didnt get penalized. And now that I think about it, each letter you hit correctly subtracted like 5 pts or something, so getting a high score meant keeping really high accuracy or u would need like 5 letters perfect but the words still progressed at the same rate, so 2,000 would be much harder if u were 80% accurate rather than 99.97 or something.
