Sandbox 2nd (Mini) Update

hi, it's been a while.

life got busy, but i managed to get some work in. They are mostly things outside of the gameplay, dealing the menus and updating the graphics.

i've updated the sandbox. Here's are some of the changes:

- Update player sprite

- Add background and multiple tilesets

- Add free-moving camera toggle

- Add slowdown toggle

- Tweak player's SFX
