How to make a block I can push?

Hey. I'm still playing around with the "maze" tutorial/module, learning to tweak a few things, and I would like to make a solid block that moves when the player pushes it, but I'm not seeing anything already built in (scripts an such) that addesses that. Any ideas how this can be done?

To be clear, I'm not looking to move a block just once, like the puzzles in Zelda. I'd just like to be able to push against a solid block and have it move until it hits another solid (like a wall)) and can't move anymore.

We won't know how to do this until the guys who made Soko Banana come out with their block-pushing module.

In Soko Banana, marp used monsters for the pushing blocks (so you can only place 4 on your screen... or you have to create other ones with a custom script).
But yeah, it's very cool. Can't wait to have that module.
