V0.3 Release

I was playing in Unity and tried writing my own gravity system and I found that flipping gravity between the Z and Y axes was really fun and kind of interesting, so I played with this a bit and after two-ish weeks of work I have these 5 Levels done. These are pretty much all mechanics additions. I plan to create more levels and refine gameplay.

Working through all the bugs have been a challenge at times and made me understand a lot about my code, and how c# works.

I would appreciate any feedback on it!

Thanks!
