Japanese 50 -Beginners Quest

Japanese 50-tone has always been the biggest difficulty for Japanese beginners. Many people are eager to learn, but because they are not commonly used, So often forget and forget, forget and back, So we developed an adventure game with 50 sounds as practice. I hope to give players a learning tool that can be practiced repeatedly and is fun. Layers challenge diverse monsters and Boss, your 50-tone ability is your fighting power!
