Incredible graphics, yet a very limited gameplay.
First of all, I would like to congratulate you for fitting this entire masterpiece in just 8 MB.
The voice acting is awesome and so is the music.
I liked the little green speaker phone videos in the corner and also the fact that two blue lines at the top of the screen flashed to indicate a checkpoint.
And lastly, the graphics were amazing with various worlds and they totally immerse you into the game.
Now for the bad stuff:
The game itself gets boring after 2 minutes and there's absolutely nothing to do except spam the shoot button.
The enemies are hardly a challenge and so are the asteroids/ buildings.
The bosses are a refreshing change but not at all a challenge.
In some cases the enemy fire cannot be dodged at all.
And lastly, I would have liked a little explanation in the final boss level and not be left floundering like a fish (or rather a Scylla Starfighter spaceship, lol)
All in all, brilliant work. I expect a lot more next time. Try using more than 8 MB and building a better gameplay, better enemies and bosses.
Cheers !
