I like some narrative in jam games. Playing this I had a bit of a feeling, that you hoped for the theme to be "two buttons" :)
The game looked good. The style is consistent, even down to the font used in the dialogue. I sometimes had a feeling that there was an element missing though. Like in a scene, where you try to plant a bomb in that tent you are talking to a soldier, but there are only boxes and chests.
The sound was good too, but it would be nice to have some more. Maybe some ambient forest sounds in the ending with "new life", or battle sounds when the battle rages on.
Having the main character be a medic fit the theme perfectly. The plot however could hold on to the theme a bit tighter. I know, I'm spying to help my army (and thus, save them), but it doesn't feel as "front and center" as it could.
Over all- I appreciate a game with a good story! Keep it up!
