Defeating the Boss...
	Escape the warp ship...
	Level skip...

Save your bomb for the Boss. Use RAM when you need extra firepower. The X beam is very powerful if you build it up. The L beams and C beams are some of the best weapons. M bombs are good for the Boss in the warp ship and the one in the city place.

An easy way to escape the warp ship is to use the M bombs on those machines. That allow you to warp. Exit the easy way.

To skip the stage 2 and stage 3 in the warp ship, exit through the hard way. This will allow you to bypass the first few stages.
