The controls are waaay too sensitive for levels 10 and 16 to be anything but frustrating. Furthermore, the mouse cursor is all but invisible on the background.
Neat game, very much liked the unusual twist, but I was very frustrated that adding the root to the potion caused it not to work. Had to try several permutations of ingredients, starting over each time.
This is possibly one of the hardest achievements on Kong; it took countless tries for me to finish it. I think the most creative part of this game, is how they use your real environment as a game mechanic; the inclusion of more interesting distractions such as the paint peeling on my wall, or the grass growing outside my house made focusing on this game terribly difficult. Well done!
