Vortexika is a game I put out as a hyper casual endless runner with a lot of polish where you avoid asteroids and enemy fire.  It features enemies that dodge the same obstacles you do and when they get hit they can crash into the obstacle rings.  I put explosive crates that explode the rest of the ring when you hit them. Even though it wasn’t a hit, I learned and built a lot of things for my next game and got a bigger understanding of Unity3D.
