This is going to be vague because it was around 10 years ago and I only ever played the game once at a friend's house, but I'm looking for a game that could have been a LEGO game (or a mini-game within) where you had to place springs, trampolines, treadmills and other contraptions to get your guy to the end of the level (think of a chain reaction, kinda like a Rube Goldberg machine). The character would start moving in a direction and you would place things in his path to get him to change direction, jump, etc.

Hopefully somebody knows what game I'm talking about, haha. I'll see if I can help anyone else out in the thread.
