Thank you so much for playing it... despite the fact I forgot the link :D !
Sorry for the exit button, the habit of making web game ^^.
Also, I'm sorry you didn't succeed to move further in the game. In fact it's our fault : we didn't let enough time at the beginning of the game to let you get familiar with the manual. Here's the process : the astronaut said you there is an "connection problems" at the "shield". So you need to look in the manual to go to the "Connection problems" page (look at the first page, with the table of contents, it indicates to you the page 8), and here, look for the "shield" part to know what to do with the modules :).
Thank you to try it <3
(And your french is pretty good :D)
