Back in middle ages it was required that women had magical silicone implants and wear nothing but sexy underwear for clothes. What didn't you know that?
On second room, make third plant eat money so it will drop a coin. Use coin on the smell device and select fish, banana and skunk. On third room, pick one robot and select the first option on the computer. Let it go through the bridge. It will give you the right colors for the first 3 numbers. Guess the other colors and grab a second robot, but this time don't use the computer. Keep using robots until you get the right color combination for all 6 spots.
Lifes and penalty for dieing? Really? That is a surprise from Nerdook... Oh yeah, like we wont simply reopen the game before losing and returning to the previous save file. Seriously, whats the point of having that in the first place? Jeez let us try again instead of punishing...
Wow this is probably the best example of "getting pre-made tower defense engine and add your own sprites" I've ever seen. Graphics are awesome, yet the game lacks SO many tower defense content its almost embarrassing. No tooltips what so ever, not even to tell us "hey placing towers here will block the path", game is extremely unbalanced (get the laser tower and win a level) and easily exploitable, to a point you must ask the developer "how come you didn't see THIS on beta phase??" (place a $50 tower and sell it constantly. You will gain free xp). Its just a big LOL on how nice a game can look and at the same time how little it was tested.
