Thanks for the new resolution. Bug found: When death occurs while in berserk mode, it seems to stay activated during every new life, making a permanent berserk mode.
Er... nevermind a few comments on my last comment. I couldn't see the top of the screen :L Make the game window smaller! I'd recommend trying around... 600 pixels vertically.
Well, the screen is too tall. I'd recommend adding more enemy types, too. Also, I suggest fixing shooting bullets shooting in the direction of the triangle. The triangle doesn't really turn as fast as the mouses movement, so I shoot assuming the shot will go in the direction of the mouse's movement, instead of the triangle's direction. If you can understand that... Although I really like that detail, for diagonal shooting. Also, I recommend changing patterns of enemies overtime, so it isn't just the same thing. Maybe some bosses. And loot drops. Also, add points. And if you want, we're always welcoming a bullet hell game.
