Create a Video for my game (to be uploaded on Play Store and Apple Store)

For my simple 2D game on Play Store and IOS (still in development), I need to make a simple video which shows the game (so recording a game session, using all the options in the game, etc..), with the game music of course, and with some colors in the background. Will show you some sample. Please show me also some sample of the work. The budget here is very low, at this will just really a very simple video. No voice over is needed here. Just play the game with the music, use the options available (like sharing, reset etc..) and have some background colors and effects around. That's all!
