I dieded. Nice little game, I loved the solid colour trail effect behind the ships, the face that I was an actual computer mouse, and that I could do Battlestar Galactica style strafing attacks on enemies (I like realistic space physics).
It felt a little open ended though, I read further down you switched projects which I think explains the lack of some stuff like more player feedback and audio. That said, it's still a really good effort for only half the time allotted, I think it could end up as a fun multiplayer game too if you expand on some of the ideas and polish it up.
Great entry to the jam, nice work!
