I could not activate the phone after I filled in all the liquids, and reading through the comments I saw I am not the only one. It drove me nuts, until I accidentally found the helpful advice from "lobn", which I repeat here (so chances are higher someone finds it): Probably the liquids/juices are not in the correct cylinders/containers (I mixed up pink and red). If all liquids are in the right container, the switch has a glowing yellow light on top. To change liquids, take the glass (empty it in the sink if there is water in it), fill one of wrong liquids in it, put the liquid into the blender, get another liquid, fill the liquids in the correct container.
While the "update" section says performance was improved and some bugs were fixed, I cannot see any of it. Game is now sluggish even during the first run, jumping is still unreliable, and the game still hangs after I beat up the green guy in the 4th level. Please continue bugfixing.
