Took me three tries to get the hang of it, but got 14700 points ^^
First try I didn’t manage to get the missiles working, not sure why. Would be nice with some heat or cooldown on the guns since I had to constantly spam them with no strategy. Would be nice if all guns were hold to fire too. Relative rotation didn’t matter as much to me since the optimal strategy was just sticking as close to the bottom of the screen so I can shoot the enemies from far away, until they become so many I can’t shoot them all down. It was a bit annoying when the enemy missiles went under the water, as it was difficult to see (and shoot) them then.
Fourth try:
