Prototype Update

Changes: 

Prototype is becoming a bit closer to being an actual game.

• Created some variables to track progress.
  • S = Stage. F = Floor.
  • There is one enemy per stage. Five stages per floor.
  • Reaching Stage 3 sends the player to the Merchant.
  • Stage 5 is a boss fight... (Fluffy is the only boss made at the moment).
• Enemies drop loot:
  • Essence - Used to make purchases from the Merchant (only 3 possible goods for now).
  • Scrolls - Useless at the moment. Future updates might use these for cosmetic/optional features.
•  Smoother (and buggy) transitions between scenes. I'm still working out how to do these properly...
• Font changed for readability.
• Fixed some bugs.
• Created some more bugs to fix.
