A little update with a lot of smaller additions, so you can wait before the next big update and the next big update devlog.

The main new changes:
-Added a new illustration
-Added a new BGM
-Reworked the initial black screen to be more interesting
-The Story and Easy difficulties, which were very similar, have been combined into one (Story). Normal has been renamed Easy but is otherwise unchanged.

The full details of the update can be seen there.
