So I added colors

I got really sad looking at the black and white and grey. looked ugly IMO so I added some colors in the background, it's a simple placeholder right now but it does help make the game look better. For game feel I added particle and trail effects for the following:
- Player movement trail
- player color change particle burst
- point collected particle burst

Apart from some game design/feel things I also updated the levels and now they feel more grounded, I also majorly changed level 7 since it was unnecessarily difficult. The level's were also made slightly easier.

that's all folks
