So I now that sometimes there are irregular plural issues, but on the last picture I had “flower” that did not score for “flowers”. Also I had “cherry blossoms” that did not score despite being the exact answer as 2 other people. Anyone else see this?

Are you sure the score was incorrect? What words did you have? 

Okay, my mistake. The score was correct. Two of my words were just not highlighted!

88 points total:

1. tree – 15 points
2. man – 14 points
3. hat – 14 points
4. backpack -11 points
5. japan – 9 points
6. walk – 6 points
7. sidewalk – 5 points
8. asia – 3 points
9. flower – 9 points (not highlighted)
   
10. cherry blossoms – 2 points (not highlighted)
    

Ah, you need to give both “foot” and “feet” to get a high score, plus “leaves” and “leaf” ...

And indeed singular isn’t highlighted when plural was mentioned more often.

A petty we can’t improve / open source.
