Really cool game.
Going through all the levels and passing through turets and etc. I really like this game... especially when it automatically saves what level you're in. Though in like more of the levels there should be gaps there and there's a ">>" pod and a ramp before the gap. While you're passing the gap... you're also getting a red diamond. That would be really cool. Also there should be specials pick-ups to kill some of the enemies.
Overall really cool game; really addictive. I hope in the future you create more games.
Great Job, 4/5
