You can lose some of your Zoombinis if you make mistakes at each obstacle. Then you have to go back on your journey to retrieve them. The game is easy to understand although the solutions may not be. You can choose different levels of difficulty as well. I could play the game for about three hours without losing interest.
Graphics are cartoon-like and fun.
Sounds are good. You can hear the Zoombinis whisper in their own language. You are also encouraged by the narrator of the journey. The game is easy to install. Send in your game review.
