Here is something all game designers need to remember when considering making a bullet hell game...1. There will be lots of enemies and bullets on the screen for a lot of the game. 2. This is a Flash game and Flash is the least efficient program ever. 3. People HATE lag. And then ask themselves if they are up to the challenge to code the game so that there will be no lag even when things get crowded. and if the answer is No, then make another genre of game.
