Very reminiscent of older blaster arcade games like Galaga. Took a second to figure out the control and for the most part the game can be beat just slowly moving the ship left and right across the screen. Enemy ships seem to favor the right side to spawn. Also most of the text doesn't show on the screen properly. Some slight enemy variety would really help the pace but you did awesome with the soul of the game coming across, the spirit of the theme, and the waves moving faster as it progressed. Would love to play again if you decide to come back to it!
