Main Menu update released

A quick and small update so you don't have to exit the game and start again to replay the level. Main Menu art provided by my gf c:

Update features:

* Added a Main Menu where you can start the game or quit the game

* Pressing ESC or the corresponding button on a controller now brings you back to the main menu instead of exiting the game (temporarily until I get a proper pause menu working)

* Changed some text to accomodate this update

The upate is a stand alone game, no need to update or merge anything. Just unpack the zip and you are good to go.
