Bullets of a Revolver
This little Freeware Indie title looks great:
You can download it now from the Blog Site as well as the soundtrack for the game. Wonderfully polished, it plays like an old school arcade game. Contained also is a game mode called Raymond's Revenge which is a homage to a Atari 2600 game with a similar name so I wouldn't let the kiddies play unsupervised.
