Summary: This doesn't come easy. It's a game for the dedicated and open minded. You have to work into it. And if you do, you find a perfectly orchestrated game with clean and fun mechanics behind the audiovisual blast. It's clearly one of the best games ever made.
Summary: Llamasoft were the brains behind Tempest 2000, arguably the most liked incarnation of Tempest. Now there's Space Giraffe, which is in the same vein. You control a ship (space giraffe?) situated on a set platform in various shapes (first level is flat, one is shaped like an apostrophe, etc), and you swivel your character around in order to shoot oncoming enemies. Complete with extremely weird sound effects and catchy electronic music, it's a very fun shooter.
