Hello Hayden,
Thank you very much for your comment. We've read and watched your whole review and cannot express enough how happy we are that you enjoyed Le Feu!
This was a student project made for tablets. As we didn't have a lot of time, we've made a fast port to Windows and Mac and had not the time to check on the bugs... Unfortunately some interactions are missing as you noticed (such as the dialogues with the two morrocan soldiers in the first trench, or the sentinel who's peeking above the trench).
If you want to see the missing parts I invite you to take a quick look at the full gameplay video (there are english subtitles)
Thank you again,
Jacky
