In the game you take on the role of Willum, who happens to be extremely Sensitive to the world around him. He is unable to touch all of the 'benign' creatures such as flies and snails around him without hurting himself! You must collect your key along the way, and get to the exit at the end of the level.
The controls are pretty standard (WASD & Space), and you can also pause the game by pressing Space.
Enjoy & Thanks!
