Hell yeah, we love a good twin-stick shooter.
This one was a little rough around the edges, but the shotgun had a great feel to it and the enemies were challenging enough (Plus, screaming eagle with a gun?). The boss fight was fun as well, and had a surprisingly varied set of attacks.
I'd like to suggest a change for the gamefeel: let me reload my shotgun in increments, where one reload-spin = 1 shell reloaded. I kept instinctively pressing reload after each shot because I wanted to feel like Arnold Schwarzenegger in Terminator 2.
