Saurotopia Windows game

Adventure game sent in alternate Earth that is at least 65+ millions of years back in time. The game will involve American pilot from the second world war being sent through a vortex into alternate Earth. After he crashes he'll have to figure out where he is and what he can do to get back to his timeline. He'll be up against enemy soldiers who crossed the same portal that linked him back to alternate Earth. He will also have to face big prehistoric beasts who are also living there.
