Stage select - Successfully complete the game to unlock all stages.

Boss Battle mode - Collect all ten Snow Boys in any stage to unlock Boss Battle mode for the Boss of that stage.

Hard mode - Successfully complete the game, and view the ending sequence. You will start back at Stage 1 with all the snowflakes and lives you had when you completed the game, except that minor enemies like snowmen with blue caps will shoot a fireball at you immediately after they are killed, making the game much more difficult.

Finding Snow Boys - To find Snow Boys, look for a place where a small amount of snow is falling, and use the Blizzard attack. This will reveal Snow Boys. There are ten in every stage.
