Space Battle

A logic puzzle. Solve the map by writing inside the grid.

Something with spaceships firing laser guns at each other, but mirrors/reflective asteroids move the paths around.

Elements

Spaceships and their guns/how they’ll shoot, misc (debris, asteroid, moon, star, something like that), mirrors

“Side X wins” or “Have 1 (red) spaceship remaining” or something.

You must fill in the missing elements to make the battle play out that way.

Every spaceship shoots a line from all their guns, at the same time. You choose its initial direction (unless already indicated).
This line can’t leave the map nor loop. In other words, a shot always ends somewhere and hits … something.
This line goes straight by default. It can only change direction when hitting other things.
If this line hits another spaceship’s SHIELD (or other debris/object/mirror), it “reflects”. (Is reflection simply “turn to left”, or is it realistic which means only diagonals reflect differently while orthogonal just reflects back at you?)
If it hits a spaceship anywhere else, that ship is killed. Yes, a ship can kill itself.
Laser lines can cross, but never double up. Clues in the map/around the map indicate where/how often they intersect (most uncertain about this?? Maybe indicating how long a shot goes on before it hits, is more useful?)

What little rules or patterns can players use to “solve” it?

Where spaceship guns are. => because of the objective, or all other sides being impossible, you can figure this out
Where debris is. => debris needs clear rules on how they spawn or what they do to figure out missing ones (this is probably the HARDEST, focus on mirrors instead)
Where mirrors are and how they face (spaceship SHIELD sections act as mirrors too) => we need SOMETHING to tell you about how shots flew to figure this out.
