This is fun! I like the concept, and I think the design of the ship (intimidating but you get familiar with it quickly) is good. One suggestion I have is to have the light make a little bit more impact. If you know where you are going, you can very easily keep the ship up as long as you want since the light is not a very harsh punishment for not keeping it, and it is far easier to just let the light run out. I think, if the punishment for running out of light was a little bit more severe, this could create a pretty stressful loop of resource management. Good job for such a short development time!
