This level is another side scrolling shooter, much like the one you played back in chapter four. Some of the enemies are much more aggressive though and fire a lot more bullets at a time, so try to kill them quickly before the number of bullets on screen becomes unmanageable.
The end of the level features a boss battle against an enemy that shoots purple blocks at you, seemingly randomly. You don't need to worry about accuracy in this fight, just keep on firing around the middle of the screen and just focus on dodging the boss's attacks.
All of the prize bubbles are fairly easy to spot and obtain in this level. Like most other levels of this type, you may have to play the level a couple of times before you're able to get all of them.
