This was fun! I liked a lot of things: the music, plot, pixelart, new aliens, new weapons, and being able to upgrade your weapons. I did struggle a bit having to move each individual weapon with just a mouse, I think if they were moveable with key presses that would help with multitasking. And the pace was a bit slow for me personally, I think a faster bullet rate and alien movement would be more fun. But overall it's a very nice game! Good job
