Simon says games

Hello forums i have a brief question,
I assembled the board + arduino uno for the simon says game listed in the arduino SSO.
After FIRST running the blink test, then altering the delay and running the blink test again my board seems to function properly. Once i upload the sketch for the simon says game nothing happens, it is supposed to produce a sequence upon start, and or, produce a sequence after the start button is pressed. In both cases nothing happens. I will attach the code file and the schematic, where should i look for the error?

Any tip is appreciated thanks.
