Sonar Kid

You're a little boy, bored as fuck, rolling over in his bed at night trying to fall asleep. Suddenly, an idea comes to your mind : Where's your dear gameboy ? You remember. Your parents took it away from you a few hours ago since you didn't eat your sprouts. Beside the fact you hear steps pacing back and forth outside of your room, you decide to go on a dangerous trip chasing your best friend in the dark through your whole house with your new app : Sonar.
