The tiny hero can transform into a legendary giant using a magic voice!
Use the giant voice to grow and repel small attacks. For powerful attacks that even a giant cannot handle, use the tiny voice to shrink and dodge quickly!
Collect food to keep your fullness up, survive the trials, and aim for a high score!
What you can practice with this game
This game lets you repeatedly practice raising and lowering your larynx, which may help with the following skills.
• Practice mixed voice and develop your vocal range
• Switch between brighter and calmer vocal tones
• Reduce throat tension, which may also reduce fatigue
Game overview
• Tiny voice: a sharp, bright tone produced with a raised larynx
See here for a detailed explanation of the giant and tiny voices!
3. Food increases your score and fullness. Hitting an enemy reduces fullness and disables voice input for two seconds.
4. At 0% fullness, the game ends. Survive until the timer reaches zero without running out of fullness!
