Somehow this game lured me in and I was pleasantly surprised! It satisfies my sci-fi thing of having multiple flying ships move about and shoot at each other, so you did that part well! Also, the choice of flat design, with couple of shades from the same color range proves you're experienced in delivering a visual atmosphere. Font seems to fit too, I like it! You did a fine job under the deadline, and it's mostly because you seem to know what you're doing right from the start :D It was a matter of implementing it all, which you pulled off in harmony!
The only thing that lacked was the audio from the shots maybe? Or idk, the rain was dominant and that's about it.
P.S. I like the idea, that only you can convert the wisps, and your converted wisps can merely kill the other dark wisps. Makes me think that I have the power to give purpose to life, while they are merely blindly killing each other.
