Actually, this game is not bad. You have no bubbles on the left wall which clears you for some nice angle shots. You essentially can shoot all the way along side and at top at will. However, that is not the best way to go about it. There are more bubbles and black bubbles above that are not visible. You will run out of bubbles if you do not aim and shoot wisely. That is why you may want to obtain the 7 extra bubble potion.
Pic 1: There are two small sets of black bubbles along right wall and are identified with a white line. The black bubbles need dropped in order for picture to lower. Each set that is dropped lowers the page more until you are able to see the last set of black bubbles and the ceiling.
You need to drop the lower black bubbles first and this is done by attacking from the bottom or between the two sets of bubbles as indicated by red line. Do not worry about. the spider bubbles.
Pic 2: Lower level black bubbles have been dropped and page has dropped some. You can now see additional spider bubbles but really don’t need to be concerned. Drop the next set of black bubbles from the top as indicated by arrow.
Pic 3: The screen has dropped more after clearing out the remaining strings of lower bubbles. and you can now see an additional row of black bubbles. Drop the lower row of black bubbles indicated by arrow and you can start shooting at the bubbles at the top as indicated by red lines as you are very close to ceiling and may put some holes in it.
Pic 4: The last row of black bubbles has been dropped and nothing left but to finish dropping the ceiling. You can see one lone black bubble in center of ceiling underlined in white. I do not know why it is there as it serves no purpose and causes no problems. Perhaps it is there just to intimidate you. Note the gold spiders on bottom which will help increase your score. I received two stars in this game using no potions and only the Precision Charm.
