SkiFree is the standalone version of the game originally included as a part of the Microsoft Entertainment Pack 3 (1991) for Windows 3.x, and later made available separately for Windows 3.x. It was then re-compiled for 32-bit Windows systems when the author found back the source code and released it for free through his website.
The skier can be steered using the keyboard or the mouse. It is also possible to jump, but the biggest ones are achieved with the help of rocks, bumps and rainbow-coloured pads. After the finish, the skier can move on until he is caught by the abominable snow monster. There are various obstacles, such as trees, snowboarders, rocks and more.
there is also some interesting background information about the game by the creator here on their website:

That domain is interesting to peruse. Definitely has a frozen in time vibe.
