As this games caters to those both blind and deaf it can be played with no sounds and no pictures; it works purely off the phone's vibrations.

Although there is an option to turn on a sonar ping, or a screen flash, or both. It also starts with on-screen instructions, as well as some statistics after a win.

By touching the screen the phone vibrates at a rate indicting the proximity to your nemesis! By planning and strategy you can deduce where he is and herd him to the corner to be captured.

Ergo this game can be played in the dark, and in silence. Handy when stuck watching a boring film!

The foe moves the same speed as you do, and never faster. It also does its best to employ tactics to evade - for instance following you if you go the wrong direction thus keeping the ping constant! It is like an ultimate game of tag where the chaser, you, have a blindfold and ear muffs!!

It has 7 levels of difficulty. Double swipe up to increase the difficulty, and double swipe down to decrease it.

It has 5 levels of vibration settings. Double swipe left to reduce the vibration, and double swipe right to increase it.

The audio ping can be enabled/disabled by a double swipe towards the top-left corner and bottom-left corner respectively.

The on-screen flash can be enabled/disabled by a double swipe towards the top-right corner and bottom-right corner respectively.

Tap the screen with 2 fingers to start a new game.

Tap the screen with 3 fingers to reset the difficulty and vibrate settings back to default.

The current version shows you the paths taken by both yourself and your adversary on having captured him.

Suggestions are welcome. For instance, improving the evasion algorithm!

This game is completely free, is has no advertising, no in-app purchases, requires no permissions except vibrate.

I also wanted a game where the feature graphic is a legitimate blank screen :)
