Testicorn – A killer app

The ghost of the

testing unicorn

that terrorizes the

city of Tallinn

@gil_zilberfeld

Testicorn App

◉ Augmented reality game where you control a

killer pony around the city

Testicorn App

◉ The real goal is to make money from whales by

offering trophies, boosts, etc.

◉ Get as many users as we can
