There is currently a Flappy Bird-esque game on the App Store called The Legend of Zeldo: Lonk’s Awakening DX. No, that is not a typo. This is an actual game someone developed, because of reasons. It’s not terrible, as far as Flappy Bird clones go. It has a unique inventory system where you can collect items as you go which affect the game play (Pelican Boots let you dash ahead a short distance, Irony Boots increase the speed with which your character flies), which almost alleviates the frustration of the core gameplay conceit. Almost.
It’s free, though. And it will likely only exist for a short period of time before the developer receives a cease & desist (even though it is clearly parody and protected, the dev likely isn’t willing to pay a lawyer to prove that), so if you think it might even be slightly interesting, you should pick it up now before it’s gone forever.
