I really love the idea of this game and had fun playing it, but it's extremely difficult for me. I think the most frustrating part is having the controls be W, A, D, because it feels like a game where I need to use two hands. I would have liked to use one hand to rotate and one hand to shoot, that way I can press the buttons much faster.
I played until I got a new top score of 13, my favourite number, but I'm sure someone will come along and beat it soon!
