Besides the small vibrations in the daily challenge, there are some other things that can be looked at.
I think the speed is a big issue since in the previous updates, you could score over 200 points in the first minute if you were fast enough. It becomes more difficult now since the animations are a bit slower and the new “skip the word you don’t know” is also a bit slow, and doesn’t really give you much, as you probably won’t remember it. My brother has 20-30% understanding and when he went to try the daily challenge 80% of it was just the animation of skipping a word he did not know, so maybe it could be changed in a way to make it more efficient?
I agree, it moves past the word and doesn’t really teach you it, so perhaps a fix should be implemented for that, maybe a pause in timer, or teaching you the new words before, or just letting you guess and get it wrong because making mistakes is a powerful way to learn.
The previous updates just made it so that it only gave you sentences where all the words you already knew. Maybe it could be that the timer is stopped, or if you get the word you don’t know wrong it will not effect you “correct streak” and only be -1 points?
If this is possibly too much I suggest maybe making correct answers worth more points so that it is a bit easier to score well on these challenges
Also one more thing, you get additional points for fast correct answers, but now that most options take time to read and understand it is does become difficult to still get the points for a fast answer with many of the options being the same and also being more than a few words long
