The game is pretty short, and it pretty much telegraphs your actions. It rides on its humour; either you will like it, or you won't.
Rather hard to discuss without spoiling, but suffice it to say, you will know pretty early on if this tickles your funnybone or not. I loved it; the writing worked very well with the silliness of the story, brief as it is.
There isn't really much to say; interactions are telegraphed, as I mentioned, so you won't get really stuck. The game is quite short. It does manage to feel "interactive" in the sense that, yeah, it could have been a short story in static fiction, but the pacing of your commands somehow works to the humour's advantage. At one point, when a certain object enters scope, it does so by extending the description of your Citroen in a way that is quite ridiculous to watch - and is the sort of humour that arises from its IF format.
Gave me a few good laughs, and these days, those were sorely needed. I do have a soft spot for French humour, too.
