Nice arcade game, as pointed there is some room of improvement for the sound, but overall it's a solid title. You might think of adding a charging bar that enable some powerup for example, in order to add variety and WOW effect.
Nice game. The sound is a bit punishing. And variety could use some improvements, but it functions. Also, I think you can hit through walls, so it's basically Call of Duty.
