Squid Yes, Not So Octopus 2: Squid Harder is an arena shooter created by Robert D. Fearon, featuring glowy graphics and eye candy that (at maximum setting) is guaranteed to push the limits of any computer setup you may have. A host of configuration options are included, allowing players to change screen size, toggle autofire, activate motion blur, or even enable the practice mode where novices could take the game for a spin without worrying about dodging bullets or colliding with enemies.

Joysticks and gamepads are automatically supported, although you could use the keyboard to play as well. The current version available for download is a beta release that will be updated with a fifth world sometime this week. (source)
