I don't really see what you would gain from a Flappy Bird clone.
That, and there's little-to-no graphics, and the title screen isn't the greatest either, with the warped letters. Also, what does "Opy" even mean?
Plus, why put the instructions on a text file when you can just put them in the game itself?
I will say that it's playable, but that's about all it has going for it.
