The older ones among you may remember SkiFree, a sports game released in 1991 in the Microsoft Entertainment Pack.
And here it is, brought back to life in this new version, playable directly in your browser.

SkiFree is a casual single-player sports simulator wherein the player uses the keyboard or the mouse to control a skier across a white background representing snow on a mountainside. The object of the game is to ski down an endless slope and avoid the obstacles (trees, stumps, snowboarders, etc.)
When the player passes the 2,000-meter mark, the Abominable Snowman appears and starts to chase the player, eating him when it catches him!
The 2D graphics give the game cool a retro feeling, but the gameplay is still addictive, and you can find yourself playing for hours to try and beat your current ski record!
