Scratch

I am a little new at scratch and I am not too sure on how to do certain things.  I am trying to make a maze.  I drew a background and made a little square sprite but I am not sure how to make so that when you hit a wall it goes back to start and when yo get to the end it switches the backgrounds and says congratrulations.  Can someone tell me how to do these things.

Heres what I have so far--

[blocks]
<when[ ]key pressed>
<point towards(
<move()steps>
[/blocks]

This is what I have for up, down right, and left.  If you want to look at my game it is at http://scratch.mit.edu/projects/shadowfall/82210

Please help!!
