Kanji reading game suggestion

I have two suggestions:

1)
I sometimes get frustrated that a wrong key stroke is immediately recognized as a mistake.
I don't know how others feel, but I would like to be able to type an answer, and then validate that input by pressing [enter] for example. Sometimes I know the right answer, but by a stupid mistake typed the wrong letter, this is immediately recognized as wrong, and the word (that I already know) will now keep popping up because the score dropped.

2)
I feel like there are a lot of words with two possible answers, but a hint is not always given, and thus often unnecessary mistakes are made. For example: with 七 you have to answer either "nana" or "shichi". It used to be that a little hint appears, as like "n_ _ _". But these hints seem to not appear anymore. Again, stupid mistakes are made, and for the next 5 games 七 keeps appearing.

I don't know whether these are things you want/can solve. I'm just mentioning.
After about 5 years, I still adore this site!

I'll look at making 1) optional in the next update.  I know for some me personally I prefer it checking what I type immediately but I can see why some people would prefer it checking at the end after they press the [enter] key.

For 2) I'll check this.  It should be showing the hints, but maybe I missed something in the last update.  Thanks for picking this up and letting me know.  There is quite a large number of options in the games now, so it does get harder testing everything now before each change.

Hi Flint,

It is perfectly understandable that not everything is possible. So I'm also good if the option is not possible. I won't make me love this site less. It was just an idea I had. And I understand that everybody has different ideas/preferences, and not everything is possible. I'm merely suggesting some things.

Concerning 2), I have the feeling that it is showing the hints if you are studying a specific chapter, but they disappear when you are studying multiple chapters together. Or maybe it has something to do with the "Kanji I am learning/have already mastered" option?
Generally, I study a new chapter by selecting only that specific chapter. Practice a couple of times, and when I'm starting to get better, I add it to the "Kanji I'm learning" option. That contains all previous chapters too. Then I'm practicing the kanji I should already know too, but I don't see the hints anymore. Maybe this can give an idea of where the coding fails? I'm just trying to help out.
