My Stepson Nevin is 7 and asked me to create him a game during the summer. He was being really good and so I asked him what should be in it. It is a platformer with almost every element animated including any stock pieces used to give the game a more living flavor. There are some pretty cool unique mechanics in it, my favorite is the bouncing block that you have to bounce off of to reach the dogs that you feed with bones to make them explode with love.
Please Enjoy a 7-year-olds creativity.
