Make a Promo. Video for a Mobile Quiz Game

We wish to have a new promotional video for our game, Quiz Jungle, which can be downloaded from Google Play Store. The current video is rather static and dull. Here are the requirements: - mp4, less than 50MB - about 30 seconds, but less than 30 seconds - landscape, 1600W * 900H - Exercise your creativity and imagination. Make it dynamic and wild, so to create a lasting impression, and lure the players to try the game. - You can now click on other players during a multi-player quiz game, to throw items at them. - Try to show the messaging feature and pet interaction. Show a scene on pet fight perhaps. - For the multi-player quiz games, try to show real players instead of robots. Tell me your relevant experience as you bid.
