thx for the congrats to me to (as if i do not deserve it)
however I agree and already admitted in using the stuff I got from YouTube the main goal of the contest was to create something people could use to train learn in a gaming way. I put a lot of work into this and succeeded in reaching for the goal.

The proposal of not using any copyrighted stuff in the future seems good to me as I am sure in all past contest you will find stuff not always belonging to the one that created a entry
