Content # 1.00 - Initial version # 1.01 - Fixed maze start cell # 1.02 - Added 'dust' to show difference between visited and unvisited trails. # 1.03 - Added settings support # 1.04 - Added animation # 1.05 - Small fix to active cell selection # # Description: # Find your way to the exit of the maze. # Longer lingering lowers your score, but eating fruits on your path # adds to score. Wander carefully. Success! # # Usage: # Use buttons at the side of to move from cell to cell until you find # the exit. Orange cells are fruits. Red cell your starting point and # a green cell the exit. # # Button: # Mid top buttons - move north # Mid left buttons - move west # Mid right buttons - move east # Mid bottom buttons - move south # # Touch pad: # Left / Right - select maze # import display, keypad, touchpads, appconfig, virtualtimers KEY_MOVE_NORTH_0 = 1 KEY_MOVE_NORTH_1 = 2 KEY_MOVE_SOUTH_0 = 13 KEY_MOVE_SOUTH_1 = 14
