I appreciate the feedback. The first iteration had movement. 'WASD' would move and 'QE' would rotate. In that version the turrets would only fire in their respective forward direction so it was much more important to have the "right" turret facing certain enemies. I think I'd like to revisit that after the jam is over. I feel it would work better with rotation on the arrow keys or with right thumb stick on a controller.
I do like the limitation of not being able to move so maybe I'll try making a PlayDate version. Not being able to move fits the small screen and the rotation should feel petty good with the crank.
