Competitors mentioned: iOS app (id6755528165), Rock-paper-scissors game with tree-based matcher/learner
Concerns raised: No real protection against bots/AI - they easily score 100, Humans are too predictable compared to AI, Leaderboard overtaken by cheating scripts
Feature requests: Frog should punch back/knock you out when it wins, Visual feedback when you miss a punch, Frog should react differently based on post-punch behavior patterns
