Buggibag's Adventure in Underground

This level has very good graphics and cool machinery. It has one of the best sound effects systems I've seen in a while and very good decorations. It's medium difficulty, which means beginners can finish it, yet it's still hard enough to give hardcore players a little challenge. Here's some pictures............

      

      

     

The way he did most of the sound effects parts was when you put a magnetic key and a magnetic key sensor on the two things you want to collide, and then connect the sensor to a sound. You can also make a sound go off when something is pulled apart by inverting the sensor.

As I said, very good level. Definitely try it next time you're looking for a good level to play.
