Welcome to this colorful world, there are 8 colors in this world: red, orange, yellow, green, blue, purple, black and white. Before playing, please make sure you can distinguish the different colors in the image above, if you can't, I don't recommend you play this game.

The world follows two basic rules

Rule 1: There is no physical collision between objects of the same color! And you, as a visitor into this world, also have to follow this rule.
Rule 2: Black color blocks all colors, including black color. White color can pass through all colors, but cannot pass black color!
These two laws constitute the basic logic of this world, and they make up the World-1.

In the World-2, I'll give you a wand which can paint and absorb color. This brings many interesting but difficult puzzles.

This game has three worlds and a total of 43 levels. But in order to pass this game, you are not required to pass all levels. And the order of playing them is up to you, you only need to complete enough levels in one world, then you can challenge the final-test level of this world, and after passing, you can enter the next world. In the final-test level of the last world, you will use your knowledge and skills to face the final boss.

As the only developer, it takes me 20 minutes to complete the puzzle at full speed. So, I estimate that it may take an hour for most players, but if you get stuck, it will probably take much more time :)

P.S. If you cannot launch the game in Windows, please download and install UE4 Prerequisites(x64).
