Learn a lot about Unity2D, i knew nothing about it before starting the jam, just made somethings in 3D. And also made my first completed game hehe. Also i got more aquainted with the Unity API . I just need to train more the parts that don't envolve coding, because i'm a programmer so i try to run away from most of the things that i need to use the unity interface, like animations and some other things hehe.
