Hi
First I like the VN mostly, there are only a few minor thing up to the point i'm at now.
SPOILER
Mostly there are a few slight issues with the german test:
The first one, even if you don't answer A every time Maddie tells you every answer would be correct and asks why it is always A. Feels off if you didn't answer A every time. To give the player the option to answer wrong but not doing anything with it, takes away from the decisions matter illusion of the VN.
Second, first and second question are not as easy as it looks, the Berlin Wall fell only more or less in the night from 9th to 10th of november 1989 (the borders were opened for freely travel), but the contract reuniting both countries was signed on 3rd of october 1990. Therefore technically the border and with that the Wall fell not until then. And tearing down the wall took until 30th of november 1990 afterwards. Asking for a specific event like when the DDR opened their borders for everyone to cross freely (1989) or when the reuniting contract was signed (1990) would be better.
And as there is no indication when the game takes place (only that it's after 1991, potentially more around mid to late 90s or later), the capital could very well be Bonn still in it, as the capital only changed to Berlin in 1999 (after changing it was finally decided in 1994), and technically it seems it took until 2006 to actually get Berlin as the Capital into the constitution, and parts of the government still are in Bonn. Changing the option for answering Bonn to idk Frankfurt or Munich or some other widely known city would be the best fix (imo), else you could add some date on the sheet which could be an easier fix.
Third, the translations are a bit off, concerning question 5 "I'm going to see you tomorrow!" is "Ich werde dich morgen sehen!" (if translated literally) but more like "Wir werden uns morgen treffen!" (= "We're going to meet tomorrow") "Wir treffen uns morgen" or "Wir sehen uns morgen!" (= "We see eachother tomorrow"), as you normally don't really mean only you will see the other person, like in only with your eyes (i mean sure it could be something a stalker means with that), but actually meeting them. And the answer to question 4 misses the "etwas" (= a bit) part of the sentence, but that's just nitpicking and not really anything anyone would notice if there wouldn't be anything else to feel off.
Other than that not having to think about decisions just having to pick the first one to get the best results every time, takes away from the illusion of decisions that matter too.
