Native german speaker here, this is pretty nice!
One mistake I found though: in the clock game the game's solution for one o'clock times is "eins", like "eins Uhr dreissig" for 1:30am/pm. That's not correct, you'd use "ein" instead of "eins", so the correct solution would be "ein Uhr dreissig"
Keep up learning german, I know from non-german coworkers how hard the language can be to get a grasp on!
Thanks for the correction! That's good to know. I also noticed it isn't dreizig but dreissig, whereas it is vierzig (and not vierssig). I have to double-check whether it is my source that's wrong or just another exception to memorize.
> dreizig but dreissig
Actually it's 'dreißig'. It can't be 'dreissig', since a double consonant like 'ss' indicates a short vowel, which a diphthong like 'ei' can never be.
A hundred years ago you might've still commonly seen it spelled "dreiszig".
They are the same thing, when you don't use latin characters.
Interesting nitpick, but I must be missing your point somehow.
>They are the same thing
No, that's in fact not the same characters (obviously?), even if they can be used to represent the same phoneme and could thus be viewed as interchangeable. I've made it explicitly clear my comment concerned spelling though.
>when you don't use latin characters.
I have no idea how to parse this, given that all three of them are letters used in latin script. I suppose one of them wouldn't be considered part of the basic latin alphabet, but then your sentence still doesn't make sense to me.
