Blur:

The kernel for depth of field blur was updated from simple:

-------
|0|1|0|
-------
|1|1|1|
-------
|0|1|0|
-------

to a bit more fancy:

-------------------------
|2^(1/2)|   1   |2^(1/2)|
-------------------------
|   1   |   2   |   1   |
-------------------------
|2^(1/2)|   1   |2^(1/2)|
-------------------------

taking corners into consideration and giving the core pixel a bit more weight.

Smear:

To give more otherworldly feeling to the ghost world a smear effect when moving was added. It is accomplished by blending together current and previous frames. This effect is not applied to the normal world.

The strength needs to be tweaked so as not to impact general visibility while still being noticeable. There’s also an idea to make it stronger in the local vision (latter image) and lighter in the full ghost view (former image).

Menu:

After listing three menu options and noticing they all begin with letter S I’ve made up my mind to have all of them like this. This may make them harder to understand, but one: once you learn what they mean it won’t be a problem, and two: the thought that they could be arranged into an S to further strengthen the theme is very appealing. Oh well.

This obviously also needs some indicator which option is currently selected, plus some enhancements like phase-shifting the individual button animations and 2 or 3 different ways for the buttons to appear on the screen.

Keep up the spirit~
