In the same vein as this question, I'm looking for an old browser-based Lego game, maybe Flash, maybe Shockwave, that I played more than ten years ago.
It was 2D, platformer-like, and puzzle-oriented. There were 3 characters on the map, and you could switch between them at any time (many puzzles revolved around getting one character somewhere and using another to perform an action, to open a door, etc). There were items to collect, maybe a shield and a sword. There were buttons that could open doors, and enemies to capture. The game itself didn't take more than 20 minutes to finish (for a child).
