This game is not a Nintendo product. This is a fanmade project. The character diddy kong although not recognizable is used. trademark and copyright for did kong go to rare or whoever owns the rights to diddy kong and nintendo. The character used in this game uses the same technique that gets the background to look somewhat 3d. the technique is to put everything inside a cube. If you want something to appear inside the cube you make it smaller. If its a side face. I tend to make the image larger so that it appears on the outside of the cube. Normally the pieces that make up the character would be part of its image. However with did kong, did kong has a higher depth so when punched his arms don’t show up on his body and instead appear when they become separated after he is hit
