Astrobob 64

This is for the MSU Game Design and Development 4: 3D Platformer final project.  AstroBob 64!  Dodge obstacles and enemies and reach the goal!

This game changes 3 things from the base project.

1. Space background and particle effects - AstroBob is fighting the Neopirates in space!  Added a starry skybox and space particles flying past.

2. Lava hazard - A dangerous flowing lava hazard; don't touch it!  Texture is from a Unity store freebie, but it needed some changes to make it work as an environmental hazard.

3. Randomized levels - The level is different every time!  There's not enough variety to be interesting, but I wanted to verify that this rudimentary PCG approach would work.
