Update

Changes:

• Added "Pause Menu"
• Added Animation for snake leaning out of Dungeon exit for Clarity. (So the player doesn't think the hero ran into the dungeon and came out the catwalk exit)
• Modified the snake walking to the cursor animation so it's slower and more clear.

Fixes:

• Fixed a bug where the windows error popup was not drawn on top of all windows. It is now drawn topmost by default.
