And a text-only version with a bit more player agency http://jsfiddle.net/dariusk/3Evm4/10/embedded/result/

Oh god, it generates history each time you flap...

I love that! Difficulty level is similar to Flappy Bird; the only difference is that slowing the game down doesn't give you an advantage in the text version.

This sums up my time with Flappy Bird perfectly

This needs a C port.

Amazing, I love it!

very nice approach!
