"Bug Machine" is an "One Level Set" from 2003 with  many  Custom Elements,  
graphic effects and also a little story.  

So it's a kind of mixture between puzzle and adventure game.
The player must produce a (mechanic) bug  to solve the level..

Like in "Jue1_Edition" I would like to point out:  If you have no idea how 
to solve the level, play the solution tape for inspiration .
