Nice execution of this idea! I mostly just swapped between shield and shoot, with the occasional heal. I tried out movement but realised it's best just to stay in the middle anyway. Maybe if there was a reason to move it might make movement useful?
I lasted over five minutes, and it didn't look like I was going to die any time soon so I quit there. I think it needs a bit more challenge to keep people playing longer. Overall, great job with this!
