Well... It was alright, especially for your first game, but there were a lot of bugs in it that could've been easily fixed.
For example, if you click on 'instructions' it'll take you to the game. Also, after you die and return to the menu, you can still see anyone on screen when you died floating by. It's a good game, but fixing the bugs (and adding sound to your gun, more guns, levels, upgrades) it could be a lot better.
Also, your comment to the other person where you said "I'm lazy, so what", if you're lazy and you want to make flash, quit now. Making flash requires time and patience.
Keep up the good work. Really good for a first game, but note the bug fixes I said.
