This game was really enjoyable as a early build. I enjoyed how the levels changed without leaving the scenes. Using the waves of enemies are a great way to separate levels within the game without directly changing the scene. Some critics of this game is that is not long enough and could benefit from looking more visually appealing however, this is to be expected in such an early build. Overall i feel that the game is good but i would like to see and endless mode to see how far you can get your score up!
