UPilot 2D prototype with keyboard control

This is a very early prototype, before cloud movement was fully implemented. There are also huge framedrops, more so than in the 3D version.

The controls are 

    S (or down arrow) to simulate breathing in

    W (or up arrow) to simulate breathing out

    Esc to exit Releasing W/up or S/down is half a breath in the direction opposite to the key released. Pressing the opposite key is the other half. The limitation is that keyboard input has only two states (pressed or not), so this is not an accurate simulation of the intended experience.
