It's always hard to rate games in foreign languages, because how much of your complaints are due to game design and how much due to your own ineptness in the language in question?
I felt dumb playing this game. In it, you are a person on a mission, wearing a red scarf, having just come out of a train station. You have a mission you need to complete!
One thing that would have helped a lot would be reading the game's extensive instructions on Itch, which include the command 'think about' (here 'penser a _____'). This is required for many puzzles in the game. I don't think the command is listed in-game; trying AIDE or INFO didn't work.
The game itself is actually pretty polished. The train station is relatively small. Time progresses every turn, and trains come in and out, with different endings happening based on different timings.
I was just replaying the game to see if I got things wrong, and I wonder if I just deeply misunderstood things or if there is a typo. In the walkthrough, it tells you to (Spoiler - click to show)Look at the Bench in the first room. But there's no bench in the room description. Other rooms do have a bench in the room description. Is there some kind of hint that tells you 'there should be a bench here too?'
Overall, I thought the puzzles and execution, once understood through the walkthrough, were cool, but I had great difficulty. If a francophone player wants to comment and explain what I missed I'd be happy to adjust my rating!
