I cannot fairly rate this game, as it uses Nintendo property in violation of both jam rules and international law.

I don’t see any screenshots on your duck life training page, but I’ll quote from the jam page: “[…] assets from asset packs are allowed, provided you have the legal rights to use them in your project.” Originality isn’t a requirement, but having a valid license to use existing assets is. So like obviously you can’t go rip sprites from existing games, but you can use asset packs if you adhere to the requirements of the pack.
