Graphics Fix

Hey!

After some testing, I realized there were many inaccuracies with graphics and shadowing in general. To make up for it, I changed some of the settings which means that it may not run as well.

I have also added jetpacks and gravity switches, which will see themselves be developed more and more as time goes on. They will be implemented into puzzles when the puzzle development starts. For now, it is purely a demonstration of the mechanics of the game. If you have any puzzle ideas, let me know!

Many thanks, the game dev
