* AwesomeMusic: Most of the soundtrack of the game is pure, unadultered ''{{Reggae}}'', of all things. For a better example here's the theme of the first stage [[https://www.youtube.com/watch?v=3vW3x0zGo7Y of the first game]].
* GameBreaker: The [[AnvilOnHead Heavy Bomb]] is quite powerful, especially against the bosses.
* SurpriseDifficulty: The colorful graphics would suggest a simple, easy-going shooter. Not so much.
