At first I skipped tutorial and thought to my self "Omg hits is super hard!!! How did others get so much points" :D
Then I went back and realized my shot follows the mouse xD Game is still hard though, not gona lie!
I'd complain that while it visually show I can move in a circle for me it seemed like its actually a square.
I also feel there was no need to limit me with just that tiny space to move. It would feel better if I could move freely around and take a better strategic use from asteroids. Them moving around me is too little helpful as I can't really predict where they are going to be when my turn ends and they usually cover me for just a split second :( Makes me wonder if you tried that internally at first and decided thats too easy.
