Version 1.2 (and 1.2.1)

Version 1.2 upgrades the game visually, adding a texture to the walls and improved button art, but I also fixed a bug where the floor would never turn to blue. Check out changelog.txt included in the download for more details. 

1.2.1 fixes a bug in 1.2 where the Development Environment text on the top left-hand corner of the menu (It's there in case I forget to disable my dev commands when making a build so I know immediately to make a new build) would reappear after returning to the main menu from the game over screen.
