The interactive lesson is really well paced: claim a cell, watch the opponent move, then build toward a reaction, one idea per step. The rule card "corners react at 2, edges at 3, centers at 4" plus the 0.5x speed on the first reaction makes the chain logic easy to follow, and the warm wooden tabletop look is lovely. I played the lesson in a desktop browser. One question: does the board ever show how many slices a cell needs, or do players learn to read it from the position? I could see myself forgetting which cells are edges in a busy match. Nice work!
