Very fun game to play, good job! If I really have to point out some stuff, I'll start with the audio: I know making music is hard, but maybe if you added a little song in the background, it would've been more immersive. One last thing is that the aliens just drop down when dead, they don't make any sound or have some knockback, that makes the game feel just a little less clean, similar thing applies to the civilians when they get their memory wiped. But overall, the game is fun, the theme was developed well and I wouldn't mind playing a match from time to time, you rock!
