This is great stuff! Akagi uses great skill to read Ryuuzaki, looking carefully at his discarded tiles and predicted which tiles he needs, which are safe to discard and which are in the danger zones. I love the idea that you have to be certain of your own judgement, and how Yagi tries to undermine Akagi’s belief in his decisions, but Akagi knows what he’s trying to do and gives as good as he gets, they both end up passing a tile when they could have won it’s SO COOL. I LOVE THIS!
…and the shouty end music is actually good/appropriate too, balances the gentle intro Closed Wait: when you are waiting for a tile in the middle to complete a straight.
