Figure it out: a quite bizarre place in some forgotten Japanese county, an undefined era and an incoming danger hangs over two joung ladies' heads. An evil entity kidnaps and locks them inside of the top floor of a tall building in a while. A horrible torture chamber is there for the two, and it's protected by two large stoneheads; the upper part is a mouth fulfilled with trusks, and the girls are tied there, hanging and wishing someone's help.

The news bounce everywhere as a rumour, and they finally echo to Nick and Tom's ears. Being two brave brothers, they immediately move in order to help the females, and enter the first chamber of the tower. They know there's a lot of foes to fight... and this is their story.

Each floor (50 in total) is made of an unique huge room fulfilled with platforms where each character can walk, slip and jump... take care not to fall in few of those nasty pits or you won't be able to come out of there. Each room is populated by odd enemies (ninja, owls, ugly dwarves, even genetically modified lizards!), few of which are not really dangerous and simply walk/jump forth and back; other enemies will charge our cold heroes or attack by throwing flames or daggers.

Nick and Tom are snowmen, so they obviously attack by throwing snowballs against enemies. To kill all of those cute enemies you'll have to throw as much snow as necessary in order to cover the whole of them. You can use the giant snowball to climb platforms or you can lift it to an upper level or throw it against other enemies (make sure to throw it quickly before snow melts or enemy will set him free and get upset!).

The thrown snowball will bounce around the screen until it reaches the bottom platform corners - then it disintegrates. Whatever enemy touched by the ball is killed and becomes a juicy cold dish (sushi plates, icecreams, etc.) or a magical potion that's necessary to increase our snowmen's skills. Also, if all enemies are killed with a single shot, a precious rain will fall from the sky: quickly get all those scrolls since they're worth 10.000 points each!

Red potions make our heroes walk faster; blue ones power their shooting capability up; the yellow one makes their shoot's range longer. Lastly, there's a light green potion which is a sort of invincibility: the snowman becomes a sort of air balloon having the ability to smash any enemies on screen for a limited time.

In the end, if you're lucky enough to find and collect a blue round icon with a snowman's face on it, a "special game" will start and last around 30 seconds: all enemies disappear, and four Pacman-style creatures will fall from the sky. You'll have to quickly kill as many as you can, because each of them is worth a letter: collect SNOW to get a bonus life.

But if you're not quick in completing stages, a sort of pumpkin-ghost appears and hunts for the snow brothers, even releasing more ghosts from its mouth, who will reveal themselves as incredible hunters and melt the brothers into water.

At every ten stages/floors our heroes are challenged by the local guardian, an enormous terrible creature, extremely snow-proof resistant - often very hard to beat!

As all levels are complete, Nick and Tom can finally engage the nasty stoneheads to the final battle. Those are placed each on a side of the screen, shooting bubbles: some are empty, some other containing potions, fireballs, hedgehog-like creatures and so on... All bubbles float to the upper edge of the screen and then explode against the tusks, making their content fall down. If the snowmen are hit by bubbles, they'd be entrapped inside and fly to their terrible destiny: being smashed by the tusks. Also, the stoneheads' mouths close slowly, making the battle area smaller and fight harder!

After completing the last stage, the cute girls are finally free, the sun rises again from the horizon, warming a beautiful grass and, as in a sort of advertisement, the sun changes into a winking snowman's head. Game title, congratulations, game over... that's all!
