1, Allow players to move up and down, it is hard to dodge bullets when vertical movement is disallowed.
2. Talking about bullets. Enemies fire orange bullets, you also fire orange bullets. See the problem? They are both orange bullets. Players will die for failing to find out which bullets are fired by enemies since both sides fire bullets with the same color. Why not changing the color of players' fired bullets to any other color than orange? Players can see better when the colors of bullets are different.
3. All the levels are very long. When players die, they will have to start from the beginning of the level. That is not good. Make sure start from where they were killed previously.

I'd have to say the best thing about this was that the graphics were decent and the gameplay did go straight through. The downsides are that the enemies just seemed to be the same people coming over and over. It was kind of fun to blow them up while they were coming down. The sounds were authentic, but it just seemed too easy to die. One hit took care of you and it was this same fireball thing. It would have been much better to have more mobility and move around the area.

You should have been able to go lower so you could get a better heads up of what was coming next. The game does seem a bit slow, but it would probably be harder if it was. I liked how everything got bullet holes when you selected it on the menu. I am just a sucker for these kinds of games, even if this one was not that good. It's far from terrible or great, so I'll put this in the middle.

PLAYED IT ALL THE TIME AT THE ARCADE

The effects are good, and the music is not bad, but:
1. Why do I have to start from the beginning when I die?
2. There are no instructions. Sure , you can say that you wrote them in the comments, but the comments are not part of the game, are they?
3. There aren't many possibilities to manoeuvre. Left-right, and when I want to pass between two planes, it's impossible. And that is one of the key gamplay attractions of a game like this.

just hold a to auto fire, if levels are going to be so long the music loop should be longer also the red squares are power ups so fly over them
