Ketchapp's developers are experts in creating casual games that are getting more and more elaborate. The perfect example is Scream Go Hero, a platform video game which the user has to control by means of voice commands.
If you whisper, you'll only jump a little bit. If you shout, you'll take a huge leap
The idea behind this game is as simple as its design. It introduces us to a ninja-like character that we'll be able to control with our voice. How? Well, very easy: we have to shout at him to make him jump each time he gets close to the edge of a gap. If we scream loud, he'll take a giant leap but if we don't force our voice so much the jump won't be as high or far. To be able to play appropriately, the best thing we can do is calibrate our phone's microphone before we start playing.
The game comes along with two game modes, one with levels and the other one is endless. During the game, we can pick up different items to increase our score and try to top the global leaderboard.
