 * Destroying a side part of the stage 2 boss just before it descends will permanently prevent the main part from attacking, rendering the boss completely harmless once both side parts are destroyed.  When a side part descends in order to perform its own attack, it is flagged as such to prevent the boss itself from attacking at the same time.  The flag is then removed when the part is raised again after its attack, allowing the boss's main attack to resume.  The 'descended' flag is also removed when the part is destroyed, but this is done at the ''beginning'' of the part's destruction animation instead of the end.  If the part starts to descend again before the destruction sequence ends, the flag will be set again, leaving it permanently set after the part has been fully removed and leaving the boss unable to resume its attacks.
-* Some of the bosses can cause bugs with the game's scrolling speed.  This bug is caused by the two bosses that appear against a looping background in stage 1 and stage 3.   The background will loop a set number of times, using a counter value to count down the number of remaining loops.  When the counter reaches 0, the game will continue normally past the loop point while the boss begins to escape.  Destroying the boss will set the counter to 1, indicating the final repeat of the looping section, before the game continues to progress as normal.  This effectively ends the stage when the boss is destroyed at any point during its time limit, without the player having to complete the full set of background loops.  Regardless of where the boss is destroyed, the loop counter will be set to 1.  These bosses can also be destroyed just before they escape, after already going through the full set of background loops and reaching the next non-looping section.  This will also set the background loop counter to 1, but as this is after the looping section has ended, this 1 will never be counted down.  This is unnoticeable until the next change in scrolling speed, when the game either speeds up at the midpoint of stage 3, or slows back down after the stage 3 boss.  For some reason requires this background loop counter to be 0 for the speed change to take effect, and the value of 1 left in the counter by the boss will prevent any speed change from occuring.  Losing a life will also empty the counter, allowing the speed changes to occur again.  Destroying the stage 1 boss just before it escapes will therefore cause the high speed section in stage 3 to scroll extremely slowly, and destroying the stage 3 boss after the final background loop but before the speed returns to normal will cause the high scrolling speed to be maintained into the next stage until the player loses a life.  As the speed decreases in several discrete stages at the end of stage 3, the amount of speed preserved can vary with the timing of the boss' destruction.

 * There are some enemies that may attack more frequently at lower rank than at higher rank.  This is because at higher rank the attack rate may be sufficiently high that the next attack occurs before the animation of the previous attack has completed.  The effect of this is that original time of the second attack is cancelled and the second attack will actually come at the time of what would have been the third attack.  At lower rank the attack animation has had time to complete so the second attack is able to come at the original time.
