Pin cushion is a discovery platformer (a metroidvania without the "vania" part), where instead of exploring a vast open world, you have to figure out how the world around you changes in reaction to your movements. To keep within the theme, there are several points on the map where the whole room shifts, with parts of the foreground sliding away into the background, and parts of the background coming forward to make new platforms or obstacles.

I ran into some physics problems during the first day, so I ended up losing about four hours to that. As a result, the map isn't finished, there is no sound or music, and the player is just a blue block. I mainly wanted to focus on making a platformer with tight and responsive controls, so that's where I put most of the time.

Most of the controls are explained in-game. The only one that isn't is that you can press R or the back button (360 controller) to go back to where you last transitioned.

EDIT: I have updated the map to remove the spot that makes it unwinnable. I have also added a link to a map that shows where everything is.
