This minigame sounds like it could be problematic if someone who tries to play it is even somewhat unclear on how its played, I think this could be easily mixed up, and jumbled. Another similar scenario happened previously with Simon Says, which along with its tricky nature led to it restriction.
I'd just like to be conscious of potential confusion that could arise and persist if this game was implemented as a supported minigame.
Placing it as an LR specific minigame could alleviate this, however by doing this we reduce its usage, therefore making it even less commonly understood among people who solely play the servers and don't use forums, which is compounded by its complexity.
It sounds fun game in concept, and is pretty interesting in-game, I just feel like its implementation could be rocky now, and in the future
