I really liked D-Day Defender, it was honestly one of the most beautiful games I`ve ever played and I had a few thoughts on it,
1: get a new narrator, I don`t if its you that supplies the narration, but the nasaily voice really blunts the impact and serious nature of the game, get someone with a good voice, female, deep male or even subtitles would be bettier in my opinion
2: don`t do in game acheivments, that also blunts the impact of the game
3: its a really good game, I like that it puts the perspective into a that of an induvidual, german soldier, I`d like to see another in the same vein
P.S. I`m sorry I originally posted this as a shout, I didn`t see your request
