Pretty nice arcade feeling. The scaling effect is pretty neat (I'm biased because we did something similar in our entry, lol). I like the art. Like Medal says, I think the shooting & reloading mechanic could have more involvement in the game. Maybe you can get a speed bonus for every enemy you take down, and you could have a small QTE to reload each bullet faster. I also think it would be good if headshots had a damage bonus. Lastly, all this is missing is a 2-player mode, haha. Nice work.
