This game has a writing style that's more like a visual novel than parser-based IF. Looking beyond the typos, (I wonder if English is the writer's first language?) the text is presented in long portions of little snippets with little player interaction.
Most of the choices the player can do don't amount to much, and the walkthrough says as such. The game part is basically one small timed puzzle.
This could have been so much more. I wanted to be the German solider caught behind British lines, rather than just read about him. I wanted to talk more with the NPCs. A few conversations would have sparked this up much more, especially before you get to the section with the puzzle.
I suggest that this author try Photopia to see how linear IF with few puzzles can be done well.
