I've had the full game on steam for a while now and enjoy it very much. It's pretty cheap and has given me hours of enjoyment. Whenever I'm thinking about games I think about the cost of going to the movies. It costs $10 for 2 hours of enjoyment. This game gives many more hours for not much more than that. I haven't played it on Kongregate so if it's a short demo I understand the feedback, just wanted to let you know what I thought of the full game since it's pretty cheap (last I checked it was $15).
