- Improved lots of defence items
- Rendering now uses sprite batches, grouping all sprites with the same image into one draw call
- A texture atlas is created on startup, grouping all images into one massive image (4096x4096)
- Various other rendering optimisations
- Reorganised image files
- Renderers are grouped into layers to be rendered, instead of being sorted
- Chosen difficulty now saves properly
- Difficulty icon is displayed in the proper location
- Held items now follow the holder
- There may be some graphics issues as a result of these optimisations
