Crayon Physics Delux is a 2D physics-based puzzle game from Kloonigames (which is really just a one-man team of consisting of the one and only Petri Purho). Based on Crayon Physics, Cray Physics Delux won the 2008 IGF grand prize.
The gameplay of CPD is very simple, in each level the player needs to guide a red ball to a star, however, the player cannot directly control the ball in anyway, but must instead move the ball by draw various objects, which is where the physics portion of the game comes in. In the original Crayon Physics, the player can only draw basic shapes like rectangle and circle, but in CPD, the player can draw anything he or she wants, meaning the player can beat a level in many different ways. When I play CPD, I think of World of Goo, not that the two games are similar or anything (aside from the fact they're both puzzle games and won awards in IGF08), but both games are just so very innovative and fun.
