I don't know why, but this game reminds on Space Impact..but now, the Santa tooked place in his sleight and he's shooting at helpless tele tubbies, pokémons and other christmaspresents. If Santa is hit from them - or crashed against them - he'll loose energy, but this can be regenerated by "collecting" little elfes, also flying around.
End-Bosses? Ok, if you see a teletubbie, throwing his (its ? ;D) handbag towards our Santa, this is veeery humorous.
Controlling the Santa is very easy, the graphic is average.
All in all you can say, that this game is the right thing for people with a little "dislike" of christmas ;D
