Very clever. Took me a bit to wrap my mind around the concept and controls. It was hard once I did and I'm not even two people! I liked it, and I think having some sound would have made it even better. 

Shooting at each other makes a lot of sense, but maybe it could have just been a constant beam instead of projectiles? Good idea, decent execution, good job!

I see what you were going for but this was very difficult to control. Either way good work!
