Professor Heinz Wolff's Gravity

Player control Professor Heinz Wolff as he tries to press a button in 100 levels. To achieve this, you'll need to build chain reactions using basic items like boards or balls. The game features physics simulation that doesn't get disabled during the building phase, so be careful not to destroy your creations.

As you progress through the levels, you'll unlock sandbox levels where you can experiment with the physics engine freely. You'll also have access to mini-games, such as building a tower that can withstand an earthquake, which you can play against other players. The PC version offers an editor to build your own experiments, while the DS version has fewer sandbox levels and mini-games.
