Great concept... needs a bit of work though!

When I played the game, first thing I found to be a problem was when selecting a plane. When you select the number of each type, you must reach 25 planes. There was no way for me to tell how many planes I had selected without doing basic math, but I didn't decide to play the game to do math, I played it to shoot a plane!

Then the moment the game started, almost all of the planes moved down the screen a bit too fast, by the time I had been able to successfully select a plane, almost half my planes were gone. By the time I figured out how to control the shooting, I was the only one left.

I like the concept, and I think it's a great start, but those few things caused the game to be a bit difficult to play, i think you should try to create a bit more high quality graphics but other than that, it's not bad. 4/5!
