Minor update to prototype

Minor update of prototype

Hi all, thank you for the great comments and feedback from the jam! I made some bug fixes and small changes to the prototype

Fixes

• Fix end of game crash
• Show the best score in the HUD in all levels
• Change transparent text to solid text in HUD

Changes

• Swapped A and B buttons
• Adjustments to player controller
  • More balanced ground vs air control
  • More friction
  • Changes for better "feel" of jump (coyote time, less gravity at apex)
• Added introductory text in the first level
