Play in Local Co-Op mode with a friend. Have your friend play as Bard. All enemies will move when either you or your friend move which makes the double speed obsolete. Be careful when moving; over-movement can kill. You will progress as long as either player survives each level, effectively doubling your chances. Dead players will respawn with two hearts on each level. Note: This technique can also be done with the same player controlling both characters, however movements will be difficult due to keeping the screen visible and keeping both of them safe. Play with the "Custom Music" option enabled and select a slow song. You can also drop any custom music to half speed, where the song sounds the same but the beats are halved.
