I really like the idea and the art looks very good. Simple and easy to learn but entertaining. Once I figured out the control with the space button and how I have to manage my fuel, I was going around saving all the ships :D
Maybe the Game could have been a little bigger size wise but that would mean to tune it all over again and at some point I realised that I can shine the light to the arrows and save ships before they are visible on the screen. This felt a little like cheating the system but it was not disrupting the gameplay.
Great work !
