Visibility has been updated, which is good! Also, bad.
This update has unfortunately broken your current save games! :( I am very sorry for the inconvenience caused but there was simply no way around it. The reason for this is that I have changed the structure of the saves to future proof them, as currently they would break if the game ever got the point where it had over 100 levels. Better to do it now rather than later!
But good news, too! This game adds a fullscreen mode, as requested by a few of you. This should fully function for all 16:9 resolutions, but it is untested on 4:3 so please be aware that it may look incredibly weird on these monitors.
That is all, and once again I am sorry for the save corruptions!
