Seasons with Thomas is a nifty little Flash game from the creator of Windosill, featuring a white creature who rides a unicycle towards the direction of your mouse cursor. You can only move towards the right side of the screen at first, following the footsteps left behind by the skiers to proceed to the next area.

Each new location that you arrive at contains at least one interactive element for the player to toy around with. It doesn't really matter if you figure out what to do with all of the objects that you discover, and the game never restricts the player from moving forward and finding new content to be amused with.

There are twelve rooms to explore before the world loops back to the frozen pond. (source: Games You Should Play)
