Something like the venerable "Same Game" puzzle, but with a larger playfield comprising pixel art pictures. This is a take on the puzzle I've never seen before, and it's surprisingly difficult, which is refreshing. It's also very useful that you don't have to entirely clear the playfield to progress; getting down to four pixels or less is fine, which is good because I'm not sure that some of the levels are actually completely clearable. I was expecting fallen columns to slide to the left to avoid leaving any completely empty columns, and they don't, which made solving the first level more difficult until I realised that! But the game works, and it's good to see new approaches to old ideas.
