World Within World will remain free for all, but the development of additional Worlds and Features will be contingent on player support.

Support development by buying the EXE to get these additional features;

• Infinite Descent Bonus Game: Features a looping set of levels which ramp up the difficulty each time you complete a cycle
  
• Saving / Loading
• Vote on Upcoming Features: Owners of the game can participate in a survey to dictate which new features are added first
• Improved graphics: Extra particle effects, and everything gets a nice drop-shadow
• Fullscreen (Sorry; GameMaker HTML5 builds literally can't be full-screen)
  
• Bundle Exclusive; Get the Pocket RPG Sprite + Tileset
