Just tried the game a bit.
1) Nice that you can chose any language subtitle combination you want.
2) Not so nice that the German localisation has problems showing special characters "ß" in the attached screenshots in "Schließ" (bottom left verb).
This should be fixed. And while we are on it. German translation for resolution is "Auflösung" not "Lösung" - it really seems as if there are no good translators in this world for indie devs anymore :(
3) There is no simple 16:9 / 4:3 option but rather the possibility to chose a certain resolution.
4) It is not nice that the menu is not looking correct whenever I chose a 4:3 resolution.
5) In 16:9 mode cutscenes and gameplay are stretched as persumed. I've made 4 screenshots. Two in 16:9 (classic mode and remastered mode) and two in 4:3 resolution for potential buyers.
6) No manual save possible or I could not find it.
Edit: There is no manual save available as confirmed by the dev but I was wrong about the single save slot. The game auto saves pretty often (explained further down by the dev) but it does NOT overwrite previous saves.
7) At least one sentence in German is different from the spoken sentence "Quatsch, das geht doch gar nicht". This issue is absent from the original release.
Edit uploaded one screenshot from the scummvm release as well.
