Pushmo is one of the most charming and complex puzzle games I've ever played. You played as Mallo, a little fluffy dude whose main objective is to push and pull blocks to save the children inside the Pushmo

It's very addictive, and it does ramp up in difficulty later on, and I admittedly skipped some levels and came back later with a little help online, but trying to figure out how to solve one of the daunting puzzles by changing and fixing some of you mistakes is oh-so-satisfying

I highly recommend getting this game before the 3DS eShop closes, and I hope this series gets another shot on Switch
