Story
Interpretation of the mobile game ‘Flappy Bird’. Control a duck by tapping any key to make him fly up, and so avoid the oncoming pipes.
Notes
Everybody seems to be going crazy over Flappy Bird at the moment, and a lot of clones have instantly appeared on the market – so why not one for the ZX81?
Written in an afternoon to captialise on the media frenzy, it’s got all the gameplay of the original, but none of the in-app adverts which have been making the author so much money recently – but you can always use the Donate button on the home and download pages to make me rich! ;D
