Windosill (2009) by Vectorpark

Windosill is a point-click-and-drag puzzle-toy, in which you guide a toy car through 10 miniature worlds.
A playable demo is online at http://windosill.com in browsers that support Flash. (Non-Flash browsers will redirect to this page.)There is also a version of Windosill for the Nintendo Switch, which supports controllers and two-player collaboration. It’s the nicest version yet.
