That was damn awesome!
I used to play this all the time with my brother! You did a great job of combining humor that can be understood even if a person has never played the game with bits here and there that are slightly inside jokes (from the game). You have a great sense of humor, and the whack-a-mole option was a GREAT touch.
Just a suggestion - maybe you could buttons on the text boxes so people can continue at their own rate? I was able to read the text fine, but I believe once there was something I misread, and I couldn't go back and read it, which made me sad because it was part of a crutial joke.
Thank you for making such a completely awesome Goemon cartoon! Can't wait for the next one! :D
