Graphics and sound effects were top notch. Really great work, especially the alien boss at the end which is really a wonderful design. Game hit a good level of difficulty, took quite a bit of damage on my way up. The shooting mechanic was a bit unusual at it appeared to pause my character for a brief second before firing off the projectile. The twist at the end was super welcome, I like how you get to play as the villain prior to being forced to fend him off. Really nice entry, fitting theme, well done.
