I realized the error with my example after I got home and forgot to update it. The issue was with:

(red=255, green=0, blue=0, repeats=1, duration=2000, steps=50)

I had copied and pasted that and should have removed the "red=", "green=", etc. I'm glad you were able to work it out.

Having the game load when the Pi starts is fairly easy, but I'd recommend searching the official Raspberry Pi forums. Last time I was there I saw quite a few posts on various ways to accomplish this.

As for allowing someone to enter a game time limit you can change your "gamelength" variable assignment to something along the lines of:

gamelength = None

while not isinstance(gamelength, int):
    gamelength = raw_input("Please enter a game time limit:\n")
        gamelength = int(gamelength) # Converts to integer
        print("Invalid entry. Time limit must be a number.\n")
        pass # ignore error and allow the loop to start over

I was able to test this code, and you will want to add it before your main game loop.

This is actually how I personally would have accomplished the task of having it end at a specific time. There may be other ways though.
