Just when you thought the Tetris-style puzzle genre had run out of surprises, along comes Dream of Pixels to turn things on its head. That's the game in a nutshell, really. It's Tetris, but sort of upside down.
Blocks still fall from top to bottom, but it is now your job to carve out the famous Tetromino forms as required from a gridded canvas. There's a skill to seeing where to remove the next shape, and as the grid creeps down any blocks left will lie untidily in the way.
Removing every object from a certain row will snap these loose blocks back up, and away from the game-ending danger that waits if your curation fails and you fill the screen. Clearing rows captures orphaned blocks back into the main grid, ready for removing anew.
