This one took some getting used to but was never too frustrating and I felt like I was doing better each time I played it. It's a tube shooter similar to Tempest but you can't really see the "tube" but you do rotate around a center point. The enemy ships can enter from any edge of the screen and swarm to the center and then start diving/shooting at the player. So similar to Galaga but you spin around the edges and shoot toward the middle instead of sticking to the bottom and shooting up. The biggest issue I had was being hit from enemy ships as that came onto the screen. I felt like they were constantly coming from behind me no matter which direction I faced. I think this was a good idea and maybe just an indicator of what's next like Tetrix has would have helped.
