This is such an interesting idea! Although I'm not sure how much it relates to the theme, I still found myself enjoying it a lot. Some explanations for each of the key types would have been great, as I still don't really know what most of them do. I was also just generally a little confused at first, but I think that was mostly because I got perfectly countered the first round, and I assumed that was just how the game worked, I didn't realize the opponent was choosing keys randomly hahaha. But there was a surprising amount of strategy here, and it felt genuinely satisfying to feel like I was "outplaying" my opponent by reading their keys and determining how likely it would be for them to use one over the other. Loved it! Great job :)
