Arrow Keys to move, R to restart, M for Main Menu, S to save progress, P to restart game, 0 to restart just the tutorial, 1 to restart just the volcano world, 2 to restart just the sea world. Unlike most scratch games, this game actually saves your progress. BTW, first time you play the game, press P or it might result in unpredictable behavior.
