+# Platformer demo
+
+## About
+
+This is a platformer game. The goal is to stay in the level, keep alive.
+When the player collects enough coins and reaches the flag, then wins
+the game.
+
+## Implementation
+
+The world is built with tilemap style.
+
+The player is implemented with SimpleCharacter node. So, using W, A, D to jump
+and move left & right.
+
+The collected coins and the player's lives are implemented with a SimpleScoring
+node. Player 1's score represents as collected coins and player 2's score
+represents lives.
+
+The player enters a coin to collect the coin. It increase "Player 1"'s score and
+vanish the coin.
+
+When the player collects enough coins and enters the flag's area, shows "You
+Win!" label.
+
+The enemies walk back and forth by setting the enemy's terminal positions within
+AnimationPlayer's "move" animation and playing it automatically.
+
+The player has a HitArea at the foot. If any enemy enters into the HitArea, the
+enemy's vanish_enemy method will be invoked to vanish the enemy.
+
+The enemies define their HitArea, too. If the player enters into the HitArea,
+nodes in HUD group will invoke their own decrease_a_life method to decrease one
+life.
+
+When the player enters an enemy's HitArea or drops down into the Dangerzone, the
+"Player 2"'s score decreases one. If there is no more life, shows "You Lose!"
+label.
+
+## Limitations found
+
+The float platforms should shake, then drop down after the player stands on it.
+However, there is no way to trigger/access the play_shake method in of
+AnimationPlayer's BlockCode node now.
