just completed red and green, how many colors aka chapter are there?

[Kelrycor]

5 chapters:

Chapter 1 - Red
Chapter 2 - Green
Chapter 3 - Blue
Chapter 4 - Yellow
Chapter 5 - End

Each chapter has a special theme (not only the color). I won't tell you now, but maybe you get it soon enough by yourself. But there is a good reason why there are 5 chapters in the game.

You shouldn't speedrun it, enjoy the view every once in a while.

If you just want to get through it, it's about 2-3 hours. If you want all the achievements, it's more like 4 1/2 hours. But yeah, it's definitely more of a sit back and enjoy kinda game.

As a rough guide I've spent 28 hours playing (and enjoying) it. I have all of the achievements but only because I cheated and used a walkthrough to find them (I defy anyone to get the 'perfect' game without assistance... some of the achievements are really, REALLY obscure).
