gamma bros is a gorgeously chunky game about two tiny pixel people trying to get home to their families in time for dinner. developed in flash, it plays with both windows and macintosh users.
the game plays like robotron versus galaga. getting close to your enemies increases your firing speed, and you can “tag” in your brother if your own ship takes too much damage. the game is intended to be played in one long session that moves seamlessly between screens of enemies, bosses and bonus rounds, and there are some lovely rewards for finishing it.
gamma bros is by “neo-retro games” developer pixeljam. the game is freeware, but they would love you to support them by way of a donation.
