This game is a little similar to Bubble Bobble. Players defeat hordes of enemies in each of fifty stages, only progressing when all enemies are gone. Enemies can either be turned into snowballs or killed by rolling a snowball over them. Unlike Bubble Bobble, though, there is a boss fight every ten stages.
This is a one-player run through the game, which obsoletes the old two-player TAS. Though using two players is faster in some levels, a multiplayer run is slower overall due to the time taken for both players to play the unskippable bonus games.
