I don't know because most projects I have come up with gameplay longer than an hour. But if the game is going to be exciting to make I will definitely do it even if it has short gameplay of few minutes.
Yes Lags... With the skill and creativity you have, I believe that this concept I told you about a simple game like you did with CB (I love the concept of beating everyone up and then doing what you want with the girl ) and his artistic style will be as successful as it always is. Like I said, I'm a fan, and I will always support.
