cool art, nice looking spaceship models (did you model them yourself?), the basic idea is very engaging and the gameplay is pretty entertaining, I've had a few runs and it was fun!
Maybe it would be nice to have more options/decisions to make in terms of controls, like if the gun would "overcharge" when not firing and then start blasting everything so the player would have to pick the best moment to stop firing
anyway, great entry, thank you for sharing!
