Objective: Survive 15 waves
For this level I figured that by placing the splash towers in the centre, that they would be able to hit enemies twice, on the way up and the way down,
Start by building two splash towers in the gaps between the pink mist. Build a generator on the mist.
Keep building generators until you have all three built.
Use the resources to upgrade the splash towers.
Build a flame tower at the beginning of the level, then upgrade it.
Build more splash towers in the middle and upgrade them. That’s all there is to it.
