awesome game
love it! it took me a min to figure out that my previous actions would make a difference later but once i did it was pretty smooth sailing from there. beat it with relative ease but on the later levels i found it helped for me to take it one step at a time and then redo individual potions continuing the steps one at a time and it would eventually fall into place.
for anyone thinking its bugged because it resets the puzzle after you click off the potion, and feel like you should blam this piece after being stuck like on level two, click the other potion after it resets (gasp) little patience goes a long way with these types of games.
