For those having low frame rate issues there is a fix on the main menu screen. For some reason this game does not run well with standard local memory settings and the developer has posted a tip on how to make the game run smoothly.
If anyone is having trouble when the pearl attack happens, try pressing Ctrl when the crab uses it. This will reset the crab's attack patterns but keep his current health.
I figured out why this why I didn't like this game. It's because the word weird was misspelled on the ending screen. At least the programmer apologized for it.
For those having trouble with the last boss there are two pieces of information that makes him almost trivial once you get the pattern down. The first is the red wurms that damage the boss only come once you break the containers at the bottom of the screen. Each time one is broken a red wurm will shoot upwards and damage the corresponding engine. The second is that a meteor will spawn from the engine you are directly below and cannot spawn from destroyed engines. Therefore the easiest way to beat the boss is to take out the engines on one side first, get the middle engine down to 1 or 2 bars left then finish the other side. This way when the middle engine is the only one left you won't have to spend as much time underneath it since it will shoot meteors very fast. Hope this helps.
