It's quite clever, but I think the pedagogical function is questionable, because I don't think that the geometric interpretation will be particularly clear to players who haven't read these articles.
The idea of the game seems to be to show people that public-key cryptography exists and can work, yet the actual method of creating the public and private keys (and the fact that the public key can be created easily given the private key and not vice versa) won't be especially obvious.
Indeed it was our idea; with the opportunity for the most curious players to learn more about Crypto, Algorithms and Math. The articles (and the whole "documentation" menu) are for the curious kids (of all ages...)
After 24h hours the game is already a success. I will for sure put a lot of effort in getting the game translated !
I think it's excellent to try to find new ways to explain these concepts. Do you think there is a path for an ordinary player of this game to come to perceive more about the properties of public and private keys, and especially how the two are related to one another?
