It's very easy, you just match a colour of a "device" you're controlling with the colour of the block in the top line. There are some simple traps and modificators down the line and it gets faster with time to make it more engaging, but I wanted to make something that would not require any tutorials or text explanation of any kind, and I think I got it. Just by screenshot it might be, huh, what am I looking at? but it's so basic that I hope everyone should get a grasp of the gameplay the moment they start the game. Also, it looks better in motion ;)
