This is a perfect arcade game you made here. Something about the deep voice on the power ups and the bullets take me back to Metal Slug days and brings a smile to my face. I really was impressed with the sinking animations on the boats that blow up. You should be proud of this. Only feedback is a few times the attacks dont go in the direction I thought they were. This game is inspiring . Fantastic job on this!
736 is about the best I got
