Startet - for another project - to work with an ESP8266 as a webserver...ended with this. This wwas my first experience with HTML & Javascript - so the code for/and the webpage are pretty ugly. ;-) But it works pretty good...except the restart after a game over on mobile. I don't know why, but it starts instantly...I'm not abled to choose the dificulty after a restart.
The Source Code is available on Github. You'll need to download two libraries from Adafruit - Links are in the Sketch.
