Downfall is a 3D arcade puzzle game (similar to Bloxter and other falling-blocks games).
It features real-time 3D graphics and lots of different boards to play.All boards have special blocks like indestructibles, dynamite sticks, snow shovels, wrecking balls etc.
Another cool feature is the import-export highscores, which lets you swap highscores with your friends.When importing, Downfall merges the highscores together, keeping the best ones.
The game is easy to learn.
