[Bumping this thread with a small update!]
I've changed the in-game gui.
Before:
After:
Changes:
The gui no longer display the sword and world level, I thought that was unnecessary.
It still show how many souls you've collected and now they're also shown floating around the upper-left corner of the screen.
The health indicator changes colour from green to red.
The assigned buttons for the sword and the shield are displayed as well.
The sword icon change when you have two swords.
The rings around the health indicator rotates slowly.
