Starting from this chapter, I will skip the game-designing part and immediately get down to the technical bits. This way, I can give you more detailed explanations about each topic. For now, let's create a new empty project on Construct 2 and a level like the one shown in the following screenshot:

This example level has all the basic needs of a platformer level. It has a ground to walk on, platforms to step on, and a floating box that contains a coin. It's a good habit to prototype game mechanics early on, so make the game space capable of testing out either one or all your systems quickly. All the sprites we use here are from the freebundle.zip folder under Sprites\Platformer pack\Base pack\Tiles. The Platformer pack folder has a lot of sprites fit for a platformer game; it is a good idea to use them in your game sometime in the future. There's one thing missing though: the character.
