Fun game
A few parts pissed me off, until I realized that if I held the left mouse button down it would use both guns.
Graphics were alright, quotes were funny, the final boss looked kind of cool honestly, I liked your design for him.
More weapons, more features, and more slaying of zombies would be great!
The music was very fitting as well.
And to be honest, I don't understand what people are talking about, impossible fights.
For one, shotguns > Missile
For two, Double Jump + Shotguns > ANYTHING THIS GAME HAS TO THROW AT YOU
