Cool little game, I love the aestethic although sometimes is hard to separate the enemies from the background. Also the beam is way more powerful compared to the missiles imo. I feel like the latter should travel faster, but nonetheless a fun game.
Thanks for playing. It sounds like you just got unlucky with the missiles, I think generally they're overpowered (see below :)). It depends on what ship you choose too, the Renegade is far better with beams whereas the Reaver is the missile specialist.
