If nothing else, you should play "Hole and Box" because it plays Greensleeves with smooth jazz. But the game beside it is equally interesting, and quite novel for the now-established block-pushing puzzle genre.

Like Donut County, you play as a hole. But instead of swallowing things, you are a hole that can attract boxes. Maybe you are a big magnet under the earth. But your goal at each stage is to drag the cardboard box out onto the dirt, so your holey magnetism certainly helps.

It wouldn't be a puzzle game without some limitations. Here, you are limited by the obstacles that stand between you and the boxes and by the fact that if you line up more than one box at a time, you will have to drag both at the same time, and you may not want to do so. Additionally, holes can only be pulled from a distance, so if the boxes are next to each other, you might get stuck.

It's kind of a mishmash of weird ideas, but executed in a great style, from the lovely, soft art style to the mellow, smooth, jazz-cheese soundtrack already mentioned.
