The overall presentation is quite simplistic, but the core mechanics and level design are where the game shows its creativity and originality. The levels are relatively easy to clear. But if you want a challenge, I recommend finishing the level with the least possible amount of boxes that can be used.
This is the most minimalistic a game can get, but that's a style that usually fit puzzle games like this, and BOXBOY is no exception. It's fun how every world, no matter how late into the game, introduces a new mechanic to keep the game original until the very end, though a few extra harder worlds that made use of every mechanic would've been nice to see. I beat the game in 1-player mode, though I also beat around half of the 2-player campaign and it's also a good game to play locally with a friend.
my favorite in the series. i even got to play it with my little sister a bit, which was super fun! expanded on a lot of things i didn't even think needed to be expanded, like the costume system. it's cool that they separated the crown and box limit goals, but i feel like you should also be rewarded for doing both at the same time considering the fact you are meant to be able to do so.
