This is really really cool! Loved the whole mechanic of loading different type of elements to the chamber and having them synthesized into different behaviors. Must be hard to design and implement. Would like some progression so that I can spend some more time with each elements, and learn what they did. (So that I don't always spam the single element into the chamber).
On a side note, would really want the reloading to be more accessible, as either movement or aiming has to be sacrifice in order to load. I can't count how many time my finger accidentally slide off a key (in the middle of the night) and made my it hurts a bit.
But anyway, a game well made! Well done!
