I manage to play your game, and it reminds me a little of the classic arcade game Asteroid. If I may suggest if you can remove the game play where the enemy pushes you back, but creates a “Defend Your Castle” situation where you must maintain in the middle of the screen to turn and shoot at a 360 degree at the enemy before they collided with you for damage. Also, have at least 50 enemies per level or include a time limit to increase the challenge of the game play. I hope these suggestions would help improve your game.
