As a game developed in GameMaker: Studio, Mystik Belle has been initially released locked to the framerate of 30fps. I have since learned the error of my ways, embracing the light of PC Master Race: )
The game has been overhauled in order to play at a far more acceptable 60 fps!

Here are the changes in the new version RC5A37:

• Added a main menu option to switch between 30 and 60 fps.
  
• Moved all control-related options into the Controls sub-menu.
  
• Added ability to map the dash function to a button!
  
• Added a Game Over-like screen. When playing on the Easier difficulty, this screen allows the player to restart the current location.
  
• Added lots of new sound effects for things that should've always had sound effects, but didn't.
  
• Added controller vibration function.
  
• Added an electric lift shortcut to the dumpster room.
  
• Re-balanced all of the boss fights.
  
• Added some new Belle animation.
  
• Added a UTF-8 font mode for Asian localization. A very incomplete Japanese translation is included with the build (anyone wants to help drive it home?: )
  
• Toned down some of the swearing in the Russian localization.
  
• Lots and lots of fixes and improvements across the board.
  
• Possibly new bugs, but hopefully not.
