Small 'Post Jam' update

Hi all!

I've made some minor changes to both the game and the Itch.io page to increase the quality of both.

To see what changed, you'll find the patch notes below!

Original 'Jam Edition'

I've preserved the original 'Jam Edition' of Tilt World as a separate downloadable .zip file. 

These are however simply the original WebGL files. This means that if your browser does not support local WebGL files you might have to set up the game in some form of server. Either locally or in the cloud.

Game changes

    + Added slight post-processing
    + Added SSAO (Screen Space Ambient Occlusion)

Itch.io page changes

    *  Fixed some typos
