Simple engine, can be great if updated
Well seeing as this was your first game you really can't expect a groundbreaking effort. Some music and sound effects are needed though I don't need to tell you that since I'm sure you have common sense. I decided to give you a seven since I think the game's engine is solid like a classic Atari 2600 game! The controls are simple and easy to pick up, and maybe a difficulty setting and temporary power ups like rapid fire would be nice. A little better artwork and more levels would be all that's really needed. So keep trying! Good luck here on Newgrounds.
