the only big problem i had was that there was almost no real reason to stand, meaning my character was crawling trough the spaceship most of the time, i'd like to see some taller enemies so i don't have too look like a toddler while blowing aliens. also the aliens hemselves i suppose are a nice homage ALIEN but the the title is kind of kind awkward as xenophobia is a fear of humans, i get that you were aiming for something similar xenomorph, but they're called that because they were hatched from humans. i'd also love to see something original.
the music is great. artwork is all lovely. the gameplay lacks though, there wasn't realy much strategy the only choices i had to make were wich weapon to pick up, and even that was mostly luck. combat with aliens consists of ducking and shooting with occasional shaking to get the rape aliens of your back. whould've been nice to see some room for tactical thinking.
also i don't get why everyone is complaining about the shift/sticky keys problem since you can just turn that warning off...
