Have fun playing this old-school platformer with zombies, ghosts and shark guns! Can you beat the zombie boss head? Trevor Monaghan (a boring chartered accountant from Newcastle Australia) has created this app from scratch with his 7 year old son, Joshua. Joshua wants to be a game developer and this is his first attempt. Joshua and his 5 year old brother Riley created all of the artwork for the game using Adobe Photoshop and Adobe Illustrator. The music was created on an iPhone using the Garage Band app.
