Anyone familiar with Tempest would definitely want to grab a copy of Typhoon 2001. Use the left and right arrow keys to move the ship around the stage, and hold the space key to shoot. A superzapper can be used by pressing the enter key. Avoid spikes when warping to the next level.

Not a standard vertical or horizontal shooter but quite simply one of the best freeware Tempest remake yet. Ace, indeed.
