SketchFighter 4000 Alpha

SketchFighter 4000 Alpha is a scrolling shooter with a focus on exploration for Mac OS X. The game was created by Lost Minds together with Ambrosia Software. "SketchFighter" uses OpenGL and a custom game engine to create visuals for all elements of the game reminiscent of hand drawn sketches.
"SketchFighter" is distributed as shareware; specifically, crippleware as only a subset of the game is playable prior to registration.
In 2020, "SketchFighter" was re-released for the Mac App Store
Gameplay.
"SketchFighter"'s game play consists of using the ship to explore different zones in the game. Players must fight a variety of enemies as they explore. Players acquire different power-up items in the game, such as different weapon types, different colors of weapons, improved shields, and faster and stronger engines. Some of these power-ups require defeating a boss; others are offered for exploring new areas of the map, including areas that can be unlocked by the player through the use of a newly acquired power-up.
The ship can navigate forward and backward and rotate. Strafing is not supported; the ship fires the direction it is facing (within a random margin of error).
"SketchFighter" offers two player cooperative and competitive modes, and it includes an Internet-based high score board.
"SketchFighter" also includes a custom level generator that the player can use to create their own levels.
