Make Some Levels For Concept "Anti-Control"

Just updated Chapter 3 for this game.

In this chapter, I introduced the blue crate, a type of crate that cannot be directly controlled by the player. To move it, there must be other movable objects supporting it, which means that once the blue box is on the ground, it can no longer be moved. 

I've experienced this kind of 'exception design in many excellent games, where certain objects are not affected by a part of the core mechanics. Adding this feature is relatively simple, requiring only slight adjustments to the game logic, but creating seven mini-levels took me quite a bit of time :(. I think there’s still a lot of room for combining blue crate with other concepts, but for now, I plan to wrap things up and continue exploring new ideas.
