Hi there! Your idea is interesting, only turning in one direction. But I think, the gameplay is a little slow. You could have added more speed to the ship, enemies and people to rescue to give your game more enrgy and dynamism for example. The sounds were also a little bit repetetive. Apart from that, this game has great potential, in just needs more energy, at least in my opinion. Good job with it!
Would love if you could check mine out too! Or not, no pressure ;)
