21-gate Mario

Unlike traditional games, every action is decided by a live 21-gate boolean logic network—a tiny symbolic “brain”. The more you nudge thoughtfully, the more autonomous and skilled the 21-gate agent becomes. This turns the simple platformer into a living demoscene of human-in-the-loop logic-network learning.

Your only control is the **Nudge** (left-click or Spacebar): a short excitation pulse that temporarily flips random gates and opens a short learning window. Successful progress after a nudge permanently strengthens those gates, so the network gradually learns to play on its own. Use the dual-panel view to watch both the world and the glowing neural network in real time. Nudge when Mario gets stuck, Reset to rebuild the level (keeping learned biases).
