Interesting game! Controls are difficult but you can get the hang of it after a couple of tries, a tutorial for the movement like an obstacle course would made it easier to adapt, another suggestion I have is to give feedback to the player when it hits an enemy, sometimes I felt I hit an enemy but I wasn't sure I dealt damage.
Also the art is unique, I felt I was playing as a bacteria killing other bacterias, I know is an airplane but the art could be transformed into a microscopic battle between bacteria IMO.
