Could you put the directions you have in the additional file in the game? Just a short description in a help file?
My dad uses his handheld to play games and little things sometimes while listening in boring meetings. Could you have a file where you can look at some cool eye candy that's built into the game from your spirographs? Just a file that plays already generated spyrographs that are really cool?
I see you have some you made but it doesn't draw attention to itself.
I like the fact that you can save your own.
Spyrographs as a name is not very eye catching. I'd call it Eye Candy, Zoo Art or something zippier. But Spyrographs is OK. I like it or would not write so much.
