+# Simon Game on BBC micro:bit V2
+# by Alan Wang
+
+"""
+How to play:
+
+1) Upload the script as main.py or in the form of .hex file.
+2) After the welcome effects, press A + B to start.
+3) Memorize the Simon sequence in each turn.
+4) Tilt the board toward indicated directions to match the sequence.
+5) After each tilting gesture, you have to return it to horizontal position.
+6) Game will end when you failed.
+7) There is no limit how long the Simon sequence can go.
+"""

+
+from microbit import display, Image, Sound, sleep

+"""
+Note: the indexes of the following tuple represent
+0 = toward up/north
+1 = toward left/west
+2 = toward right/east
+3 = toward down/south
+
+Since gesture "up" in micro:bit means "north side up",
+I inverted the direction here.
+But you can change the items of gestures, images and notes
+to customize what would be shown and play on micro:bit.
