Starting Bubbles: 75
Recommended Potions: Rainbow Bubbles and + 3 holes in the ceiling
Points needed for 1, 2, 3 Star:
Take a look at the Strategy Pic to the left. You can let the virus drip down as far as the Upper Bomb, if you miss that dead line you have probably lost the level.
When you think that the ceiling soon should be visible, you are probably in a position, that makes you shoot above the viruses to get the virus cluster down. If you haven’t a clue of what the bubbles above the virus are, you might need both Rainbow bubbles to get the Infection down. I made a “worst case scenario”-pic to demonstrate why it is wise to spare the RB Bubbles until the ceiling. If they aren’t indeed needed, you can use them successfully to get some extra points with Green Spiders.
Special Warning to those of you that use the Charm of Salvation; The virus will probably spread way to low, if you don’t focus on taking out the right side before the Bombs.
Please watch this video for EI15-8, made without any Charms, if you still need guidance.
