What's green, cute, and crawls on your shoulder? It's a creeper - and it's going to turn into a butterfly when you complete the puzzle!
This game is like a child's version of The Incredible Machine. You must solve puzzles by building and putting tools in the right places, then watch your little creeper as it turns into a butterfly and flies away.
If you get stuck, you can always ask the Professor's advice!
The game is not complicated; it's somewhat fun, and very cute. I'd give it a 3 overall. Even though it's rated quite low, I'd say it's a must-have if you ever plan to revisit the innocent days of your childhood.
