Tank Defence - 1 Week Game

CONTROLS A and D to move, Space to shoot. A game created in a week as a personal project between a friend of mine and myself. Testing to see what I can make of an old arcade game as part of a larger Arcade Game Project Im working on. Its my own take on Space Invaders but with my friend Thomass custom music tracks and all other assets and programming created by myself. Constructive Criticism would be handy as I would like to know where I can improve and develop as a developer :) Post your score in the comment section below!!
