A Gravitate Square

It looks like a normal square, nothing special, but it's not just nothing special or a normal square, it's a square which can change the direction of gravity whatever it wants by some magic.

Come to this cool square and start your journey with the special power which controls the direction of gravity. There have about 25 levels waiting for you to pass through.

I started learn Unity about five months ago, and I really need some feedback or recommendation from you! The feedback also can include my English or anything else, your feedback can make me improve faster.
