From Luka Grgurovic:
The city is in great danger, criminals are taking it, and the only one who can stop them is our green Incredible Flappy Avenger. He is in a hurry to kick some bad guys, but there are too many obstacles on his way, and the only person who can guide him is you my fellow player. Get your superhero as far as you can in this thrilling endless adventure and prove yourself as the best protector of the city in the world.
