This small update makes a few improvements to the launch version of the game:
[list]
[*] Fixed flickering tile edges (z-fighting)
[*] Allow game window to be freely resized
[*] Ctrl+Z is now bound as shortcut for undo (alongside the U and Backspace keys)
[*] Reduced save frequency to improve performance (every 30 seconds, and whenever you quit)
