For a puzzle game youd probably want to do some research on pushing objects*, and buttons/triggers**. Switches*** are another relatively simple but commonly used puzzle element.
There is more, but most are just variations of those. (Ie, Objects that when you push once, they slide until they hit something, Buttons that only work when something is on top of them)

*Search the forum, you should find posts/snipplets that explain it all.
**These are simple, you just need to use the Entered() proc, and sometimes the Exited() proc.
***Switches are easy, you just have to decide how you want to turn them on and off.
