Hey Alariann,
This is a very good game!
Next step for you dude is just baking some more levels and maybe add some different enemies that can interfere with our rounded square. Dare I say a baddie that can roam the middle areas that you have to avoid. Yes...I am evil.
Maybe create a longer musical loop as well. After about 10 minutes, its gets a little repetitive haha.
Good job!
