Infinite Fame is a monochrome shoot'em up made during Ludum Dare 16, whose theme was "You Only Get One"
It consists of a single boss fight against a mothership. The trick is that you only have one bullet and have to wait for the vulnerability point of the enemy to show before firing it. You lose the game if you get hit by enemy fire or if you miss your single shot.
Infinite Fame is made in HTML5 and is playable in a web browser, although an .exe version also exists for playing it standalone on windows platforms.
