Morpheus' Helpers Alpha Build

Update visuals of sprites to be more colorful, Changed background to make objects in foreground more noticeable. Added level 2.5 to intro a new way to interact with the music walls. The level is meant to be an easy level. Added main menu and pause menu. Hold P to pause. Swapped levels 8 and 6 as I think its better to ramp up the difficulty. Use color palette of purple, pink, dark blue, light blue and yellow to give the game a central color scheme. Added frames to aminations to make them seem more natural instead of blinking. Removed music wall from level 7 to reduce visual noise of space where player spawns.
