怒首領蜂 ~ Dodonpachi - 2-ALL Clear 267 Million

First clear.

Dodonpachi was Cave's first attempt at making a bullet hell shmup and is the one that really revolutionized the genre as we know it today.

Scoring in this game is based on a chain system. Killing enemies raises the meter in the top-left and quickly runs out when you aren't. When it runs out you break the chain, it takes like a second for the meter to run out. Killing enemies with shot gives you more meter than using laser and lasering enemies makes the gauge freeze at a tiny amount left.
In the 2nd loop you get more time before the meter runs out.

There is also a maximum bomb bonus. The more bombs you pick up while at max the bigger the per-frame bonus score gets. It gets pretty huge over the course of the game.

First loop was almost perfect in terms of scoring, second was pretty terrible though.
My best score at the moment is 294,186,450 but that wasn't a clear.
