Ice Breaker is a Flash game that contains 40 different screens. Each screen is a type of puzzle where you chip away ice or ropes in order to get you Vikings into their boat.
It sucked a bit of my time :)
PS. If you kill one of your guys on a screen and have to do it over more than two, then you score goes back to zip.
Give it a try, fun little game!
