I made a game called Displacement that is a Sokoban-style block pushing and pulling game where you activated switches and clear paths to the exit. The novel thing about my game is that when you push or pull, every block vertically an horizontally aligned with the player moves as well. This means you really have to think a few moves ahead when trying to solve a puzzle. At the bottom of this post is an example of a level about 50% of the way through the game.

If that sounds interesting to you, let me know what you think of Displacement: https://ldjam.com/events/ludum-dare/46/displacement
