Wow, that's awesome. Definitely full 5 stars for theme and innovation. If that's not "strength in numbers", what is^^
Also pretty nice graphics style and cool soundeffects, even with voice-overs.
Just Endboss 8 was too hard for me unfortunately :-D
I also appreciate that you made it playable windowed and in fullscreen and even made the keybindings customizable (because the default ones would be a bit strange on a german keyboard^^)
All in all congrats to a great entry!
