A bullet hell certainly is out of control. I like that the arena is round, instead of the conventional square shape. Though, I wish there was some explanation of how to play the game. There are red and orange bullets, but they both do damage. I would suggest orange being my bullets and red being the enemy bullets. It would also be nice if my bullets only damage the enemies, while the enemy's bullets only damage me. Someone also mentioned that there is a shield mechanic, but I didn't discover that whilest playing.
