Press the green flag to begin. Go through the maze to find Olaf's head. Use the arrows on your keyboard to guide Olaf's body through the maze. If you hit any of the black lines, you will automatically go back to the start. If you finish and want to play again, press the green flag.
I added the song Unmeltable Me to the music, made the ending better, improved the maze, and edited the backdrop. All other credits to @Halwho.
