Really cool concept of the of the changing weapons and nicely implemented, I do feel the cooldown on firing was too slow, I spent way more time running around bored, especially after throwing away a weapon I couldn't use. It also felt like the machine gun(?) regularly misfired (or the bullet had a collision issue with my character. The different enemie AI's were solid and I love the trying to juggle targets and weapons. Really cool and well implemented concept. You should definitely expand on this.
