Game: Bumps

Physics-based puzzle games like Peggle have proven to be very successful, but an integral part of Peggle's gameplay was the random elements of chance that made each game different. Take away that element, and you end up with Bumps.Essentially a large series of  drop puzzles, Bumps is about dropping colored balls onto a series of platforms and letting the games excellent physics engine work its magic to collect like-colored keys. (The keys unlock cages filled with captured Bumps that are being stored away to be eaten by some alien invasion, but other than the opening sequence, it's just a foil for the gameplay.)
