neat-o graphics! and I like the old arcade movement, nice game

I see that the 'L' was meant to represent the current wave? I at first thought this, but whilst playing it was at one point '2' and then lowered down to '1' again, so I presumed that it must of been displaying something else.

The game's okay, and I noticed it was entered as an entry for Bugaham's contest on the forums.
The sounds were fine, as were the graphics as a whole as it suited what was aimed for. However, the reflection of the bombs can cause for minor confusion when the game gets a little more frantic.
I feel that avoiding bombs and shooting planes somehow got a little tedious, and usually a high score addition would partially solve this issue. The fact that the current default high score is '25000' is a little annoying though as any scores obtained lower than that are in vain. An empty high score on the first time of playing would of been much more appreciated.
As for the power-ups, I tried collecting them all whenever I could. After obtaining one, I had a 3-bullet power-up. Then I got another power-up and I got a 2-bullet power-up, therefore eliminating the purpose of collecting it.
I also didn't fully understand what 'L=' was for some reason. Is that the level of your current power-up?
And the power-ups I obtained usually passed by the top of the screen for some reason, of which is a complete deathtrap due to the falling bombs, of which move as they fall (which subsequently causes for more difficulty).
The game was okay, but it isn't anything that's going to get me glued. :D
