Andrea, plase take a careful look at this paragraph of the contest RULES *again*, that can be found
in this link:
"Although original games will be preferred, non-original concept games will be also accepted. This includes conversions from arcades and/or other console or computer systems, as well as adaptations of already existent games. However, recompiled games are not acceptable. Already released games or hacked games will not be accepted either. Also, direct graphic or music rips from other authors used without permission will not be acceptable. In case of doubt, the organization is entitled to ask for proofs, such as the source code of the game. Any suspicious game would be disqualified if the organization decides so.
Taking in account the video you provided, it seems you are using *again* ripped graphics. This will NOT be accepted by the organization in any case.
