Scratch

Scratch is kind of limited for those kind of physics, but I suppose you can put sensors on each side of a box's bottom (preferably switch-to costume sensors instead of sprite sensors so each box doesn't need more sprites), and make them check if they are touching the level. 

If one is touching and the other is not, turn towards the sensor that is not touching.
If both are touching, change x velocity by sin of direction (assuming direction=0 is when your box is on a flat surface. (this is so it slides down a slope)
If both are not touching, fall.

Then you can include wall sensors and all that other stuff separately.  I can write a script in a second if you want.

Ok, here's the best I can do on short notice- I ripped apart my slope detector engine and rewrote some things, this should work:

Oh cripes, didn't realize it was that long until I put it here.  There's probably a MUCH simpler method.
