Z for one gun, and X for the other :) This part of the tutorial (where they say attack the enemy ships manually) was quite confusing. It said something about pressing the highlighted button and attacking the enemies, but this highlighted button was quite hard to find. maybe add some arrows to help ...
Since I am usually too lazy to write in forms, would it be ok if I report bugs in the Discord Channel?
or would forms be a better idea because more people are active here (and the developers (you))?
