Small UI Changes

Tonight I made a few small changes to the UI after receiving some direct feedback. I also updated the sprite for one of the enemies to make it more intimidating and made one rhyme slightly less awkward.

The two main UI changes were:

• Changed cooldown text to be more polished, remove a lack of rhyme, and make the spell details legible behind it
• Removed redundant and confusing pause menu, put the fight restart button in its place and put password in a more prominent place.
