Downfall has nothing to do with the classic Hasbro game of the same name, but plenty to do with Tetris.
It takes the original Tetris game and adds a few variations and some new features, along with placing the game in a 3D environment.
There are 24 different game environments to choose from in the full version, but this demo lets you play only a few.
Unlike Tetris each falling block is made up of three different coloured squares, which can be rotated into any order you like. This means that rows of four or more identical blocks can be created diagonally in addition to horizontally and vertically.
