Hey there I am addicted to it also. Currently on level 42 (no pun on the music group)
Two things I thought might be helpful for people who are getting stuck.
Alot of times once you hit a switch to get oil or fire pots dripping, you can often use that actual stream of oil or fire to trigger it's own switch.
if you are trying to bounce one of the liquids using a spring pad, keep in mind that if you bounce it very close to vertical, it will often come back down on the spring pad (now with more momentum) and bounce again even higher.
i'm on level 25 (got to this level in one sitting) and its a great game. My hint is that if you find yourself stuck without enough bounce go back to your path and try to swap out some big bouncers with some smaller ones to give you more bouce where you really really need it. I know that might come out confusing but there's no easy way to explain it.
