OK...there's this ancient LCD game that I really want to play again (or download if it exists) but don't know the name...hence I need some help.

The concept is very similar to Sokoban, except instead of a guy pushing around boxes and having static walls, you control a dot in a maze. ALL the walls in the maze are pushable, provided that there is a space between them. For instance:

| | |<-- you can't push these walls because there is no space
| | | for a wall between them
| | o |<-- You (the dot)
| | |

| | <-- you CAN push these walls because there is a space
| |
| | o <--The result of pushing the wall. You (Mr. dot) can
| | now go either up, down, or back.

Anyways -- you can find a similar game to this here. But it's only got one level so it's more of a taste of what the real game is like. I really want to know the name of this game!

(btw -- before any admin might be tempted take this post down due to the link being to a GB rom -- the rom is freeware )
