New levels are coming, we promise! In the meantime, we're working on smaller improvements like localization, the first of which is for Simplified Chinese. The language can be changed under Settings in the main menu.

This update also does the following:

• Changes the "paint all vowels" challenge to "paint the letters K-E-Y-S."
  
• Updates the behavior of the balls to (hopefully!) prevent them from getting stuck in the corners of the keyboard.
  
• Adds a halfway setting for music and sound effect volumes. This is a stopgap measure until we're able to rebuild the UI with full-blown volume sliders in mind.
