I think the other Germans here will agree that Berlin isn’t ”Germany” - meaning it’s not the typical German city, it’s very international and modern (someone else can chime in and add to this) Since you mentioned Munich, I would recommend going there first perhaps, since it’s more ”German” than Berlin…
Also playing DK tropical freeze!! Just finished the final boss, agree on the world 6 being hard, a lot of sweat to clear them perfectly, so good luck haha. Gonna open the rest of the levels later!
