-# Go Jetpack
-by [Branson Camp](https://github.com/bcamp1) using [Pixel](https://github.com/faiface/pixel)
-
-Welcome to Go-Jetpack, where you explore the skies using WASD or Arrow Keys.
-This example showcases most of the fundamental pixel elements described in the [Pixel Wiki](https://github.com/faiface/pixel/wiki)

-![Screenshot](https://github.com/bcamp1/pixel/blob/master/examples/community/go-jetpack/screenshot.png)
+Rolling cloud effect added to the Jetpack demo.

-# Isometric view basics
-
-Created by [Sergio Vera](https://github.com/svera).
-
-Isometric view is a display method used to create an illusion of 3D for an otherwise 2D game - sometimes referred to as pseudo 3D or 2.5D.
-
-Implementing an isometric view can be done in many ways, but for the sake of simplicity we'll implement a tile-based approach, which is the most efficient and widely used method.
-
-In the tile-based approach, each visual element is broken down into smaller pieces, called tiles, of a standard size. These tiles will be arranged to form the game world according to pre-determined level data - usually a 2D array.
-
-For a detailed explanation about the maths behind this, read [http://clintbellanger.net/articles/isometric_math/](http://clintbellanger.net/articles/isometric_math/).

-
-Created by [Sergio Vera](https://github.com/svera)
-
-This example shows how to implement an infinite side scrolling background with a depth effect, using [parallax scrolling](https://en.wikipedia.org/wiki/Parallax_scrolling). Code is based in the [infinite scrolling background](https://github.com/faiface/pixel/tree/master/examples/community/scrolling-background) demo.

-Credits to [Peter Hellberg](https://github.com/peterhellberg) for the improved background images.
