`Gravity` add more levels

[ZacharyPatten]

The Gravity game has 15 levels at the moment. It would be nice to add more.

Some possible ideas:

• Levels with multiple player blobs. You would have to get each blob to the goal or perhaps separate/multiple goals.
• Levels that are not stationary. Perhaps the goal moves around. Maybe spikes appear/disappear or move around.
• Keys that make walls/doors open allowing access to the goal.

@Fuinny If you didn't see I added another ~2 levels using the toggle mechanic you added. :)

Hey, that's cool, glad you liked it! Maybe I'll add more levels later or come up with something else ¯\(ツ)/¯
