Icebreaker 2

Icebreaker is a Flash-based puzzle game in which the player has to free
Vikings frozen solid in the ice, and get them safely in their longboat. By
drawing a line with the mouse, the player can specify where to cut through the
ice. From then on, gravity and the icy surface do the rest.

Levels become increasingly more difficult, as they feature elements like
different motionless and moving obstacles and rock surfaces which can’t be
cut.
