I do not believe this game has been mentioned on the master list yet.
Within A Deep Forest (WADF)
WADF is a 2-D side scrolling platform/puzzle/adventure game created using Multimedia Fusion. Where you take control of a scientfic experiment (which coincidently happens to be a bouncing ball) that has the task of defusing a bomb that threatens the earth.
Key strengths of this game include refreshing puzzles, atmospheric gameplay, and a healthy length of playing. If you have played the game 'Knytt', you will probably also enjoy this game.
