As the day started, I forgot Ludum Dare started. I wasn't going to participate if I couldn't think of something small, fun and interesting. Luckily, I found a concept that might work.
It started off as this idea:
"You have an unstable laser. You can shoot it to kill enemies, but with more use comes more unstable-ness."
I was planning on making a platformer with a character walking around with a laser rifle. But that idea passed, since it would require me to create a lot of animations ... something I simply cannot do. It would take the full 72 hours for me to just make a character animation.
Luckily spaceships can have laser guns and those need little animations, like rotating and stretching. As you can see below, I have already made the laser, since this is the most important part of a game about a laser. Just adding a line renderer, particle effects and bloom and the result looks nice. Of course I will tweak some values tomorrow, but the result is pretty cool already.

The unstable part can be found in the actual laser. See, a laser is made with multiple different parts. It starts with an energy source which starts a beam. Magnetic coils make sure the beam is as straight as it can be. The first lens makes sure most of the energy is passed through the entire crystal, which will give it it's red color. The second lens then focusses the energy to a narrower spot, making it sure it deals as much damage as possible.

Unfortunately, things can go wrong and any component can shift which messes with the alignment. Luckily you have control over the rotation of the components, so you might be able to fix it. Or you can use the mistakes to your advantage ;)
