What a strange, cute little puzzle game. The main gimmick is that you have a controller that selects a color (think of it like an artist’s palette). All the obstacles are colored, and when you select a color, it “paints” the sky that color. This “removes” the obstacles and lets you walk through them. From there, puzzle and platform away!
There’s no real plot that I could see. It felt kind of like Braid (or any Jonathan Blow game), where there were hints of a plot, and if I really wanted to, I might be able to see how the various threads combine. The game is probably like 8ish hours long. I really only got stuck on two levels at the end where you had to do some real platforming.
If you have a spare weekend, I highly recommend this game.
