Hi thanks for the feedback, this is indeed the idea behind the game, timing to hit the tubes with the drop, as you progress tubes get faster and drops as well. don't hit the lab rats dough!
I agree that it was a little too hard. I would also show the ingredients to mix colors in the first few levels.
Hey, thanks for feedback, the ingredients are behind the HELP menu, (question mark "?"), if we made it too easy to hit the tubes, its possible to finish within minutes ;-P
