Nice visuals and atmosphere! Unfortunately the gameplay is a bit too easy to cheese since there's no penalty for defending. I was able to get pretty far just by defending whenever the enemy had a shot and waiting for them to expend it, then either attacking or reloading, then repeating the process. I understand why it's so exploitable though, given what you commented about the short development time. Still, it has a quality interface and the concept could be improved with some altered execution!
