itch.io

A popular game from 2013 where you must tap a bird to dodge pipes. Many clones & fangames were made because of the original game's success. 

Pixel Art refers to the charming, simplistic, retro/renaissance style of very-low-resolution graphics, such as from the 1977-1995 Atari, GameBoy, & Super Nintendo (SNES) eras.

For that old school look and feel.
