Flappy Bird vs Flying Otto

flappy bidr Flappy Bird is a mobile phone game developed by Dong Nguyen, a Vietnamese freelance game maker. The aim of the game is to finish the levels without hitting the bird's head in the world full of pipes.
The green pipes in the game where the player controls a bird belong to the Mario game world and were technically theft and used in the game without the permission of Nintendo.

As a matter of fact , at the end of the game , the real mario comes and shoots the bird and disables it .

This game in itself is a good example of how much money a game can make even though it contains stolen graphics.

The Flying Otto game, made by the Gamikro team in 2014, similarly aims to finish the level without hitting obstacles like flappy bird.
Unlike Flappy Bird, Otto is a very entertaining game.
